Web 2.0

Web 2.0


What is Web 2.0?

According to Wikipedia, the phrase Web 2.0 refers to "a perceived second generation of web-based communities and hosted services (such as social-networking sites, wikis and folksonomies) which aim to facilitate collaboration and sharing between users".

Traditionally, the World Wide Web has been a one-way, publisher to reader, medium. The distinguishing feature of Web 2.0 is that it is a bidirectional medium, where content (text, image, audio or video) is contributed by people who interact with the website as well as people and organizations who manage the site - in other words, it is the "read/write web".

This wiki space gives you a flavour of the world of Web 2.0 and collaborative tools, and some suggestions to guide your use of them. There's a Glossary, and some Web 2.0 Guidelines on using external services. Please feel free to use the Comment option at the bottom of each page to leave comments or suggestions.


Characteristics of Web 2.0

1. Contain web applications have characteristic and function like application in computer desktop.

May be carried out further through web browser and does not require software installer on PC.

Such as javascript application , java applets, php and so on.

2. User-generated content (interactivity): Enable all the users giving opinion, comment, write articles and so on like blog, forum, Facebook, Friendster, MySpace, Squidoo and so on. If in web 1.0, user just reading article in website, in web 2.0, users also can be subscriber and contributor. Include: photo sharing platform such as Flickr and video sharing such as YouTube, GoogleVideo.

3. Related enable users each other. Applicable platform including MyBlogLog,

to blogs, or add a friend like Friendster or MySpace. Contrasts with link usual, interactive and in MyBlogLog example, enable users fill the personal information and see the connection between another users.

4. RSS feed and RSS reader usage in web site or blog. Can give instant information to users when the site was updated. Users do not use URL and check out the website everyday.

5. Open Source script 's (OS) usage, either collectively or half-OS. Script on wordpress.org, wiki, mozilla, sourceforge and so on.

6. Folksonomy usage such as tagging, tag clouds and so on giving the category to webpage, links and photos.

7. User-friendly interface. Not like web 1.0, usually do not really user friendly, Web 2.0 sites is easy using for anyone because it include WYSIWYG 's characteristic (what you see is what you gate). Take A Look Friendster and Facebook - so easy to do it for beginner!

8. Clean layout. Easy navigation. Not complicated.


Differences of Web 2.0. and 1.0

Differences of Web 2.0. and 1.0 are restriction in Web 1.0 which permit internet user to see into that website and see one by one content in the website. Web 2.0 make possible to internet user can see a content website without visit to main URL. Apart from that, Web 2.0 ability can do drag and drop, auto complete, chat, and voice such as eligible its application desktop, like operational system, using by AJAX support or various plug in (FIRE). That will be change developer paradigm software from distribution products to be distribution service. Although the other character, consumer collaboration and involvement can help strengthen difference in Web 2.0.

Examples:

Web 1.0 Web 2.0
DoubleClick -> Google AdSense
Ofoto -> Flickr
Akamai -> BitTorrent
mp3.com -> Napster
Britannica Online -> Wikipedia
Personal Websites -> Blogging
evite -> Upcoming.org dan EVDB
spekulasi nama domain -> Optimasi Search Engine
page view -> Cost per click
screen scraping -> Web services
publishing -> Participation
content management system -> Wikis
direktori (taksonomi) -> Tagging(”folksonomy”)
stickiness -> Syndication


The Advantages and Disadvantages of Web 2.0

I wish to go over the key advantages and disadvantages of Web 2.0, and this will give readers the ability to decide what they think. However, to understand the pros and cons of Web 2.0, it is first important to know what it is. Web 2.0 is an enhancement of the existing Internet. To break it down into a single definition that is relatively simple, Web 2.0 is a system in which online users become participants rather than mere viewers.

With Web 2.0, information can be pulled from a number of different places, and it can be personalized to meet the needs of a single user. Applications can be built on the existing applications that comprise theWeb 2.0 interface. It could be said that Web 2 .0 will allow the mass population to communicate with each other and spread ideas rather than receiving their information from a single authority. Based on the descriptions above, it should be easy to see theadvantages of this system. Information will flow freely, and people can express their ideas without fear of repression. Web 2.0 would make the Internet a true democratic system, a digital democracy.

The population as a whole would become more informed. Instead of getting information from once source that could have an agenda, they can receive their information from multiple sources, and this will allow them to make better decisions about the world around them. A good example of this is the ability to read newspapers from various countries other than the one you reside in. You can view events from more than one perspective, and this allows you to be a more well informed person. Another powerful advantage ofWeb 2.0 is communication. It has become obvious that the Internet is one of the greatest communication mediums in the world.

In my personal opinion, the Internet surpasses even the telephone and printing press. The reason I say this is because the masses can communicate with each other without the oversight of governments or corporations. This has created an environment where ideas and freedom is allowed to flow unrestricted. People can communicate from around the world for a fraction of the cost they would pay to make an international phone call. Web 2.0 will make the Internet more personalized. Everyone has different needs, and Web 2.0 will allow each individual to have information that is tailored to their needs and interests.

However, there are a number of disadvantages to Web 2.0 as well. Unfortunately, this information is rarely discussed in the media. Too many people push the benefits of Web 2.0 without taking the time to educate people about the problems. One of the key problems with Web 2.0 is dependence. I'm a good example of what happens when you become heavily dependent on the Internet. If your connection should go down, how will you access the information that you come to depend on? Because many web services will be offered for free, they won't be secure, and they could easily be targeted by hackers.


Web 2.0 deployment IN BLOG APPLICATION

The term web-log, or blog, was coined by Jorn Barger in 1997 and refers to a simple webpage consisting of brief paragraphs of opinion, information, personal diary entries, or links, called posts, arranged chronologically with the most recent first, in the style of an online journal (Doctorow et al., 2002). Most blogs also allow visitors to add a comment below a blog entry.

This posting and commenting process contributes to the nature of blogging (as an exchange of views) in what Yale University law professor, Yochai Benkler, calls a ‘weighted conversation’ between a primary author and a group of secondary comment contributors, who communicate to an unlimited number of readers. It also contributes to blogging's sense of immediacy, since ‘blogs enable individuals to write to their Web pages in journalism time – that is hourly, daily, weekly – whereas the Web page culture that preceded it tended to be slower moving: less an equivalent of reportage than of the essay’ (Benkler, 2006, p.217). Each post is usually ‘tagged’ with a keyword or two, allowing the subject of the post to be categorized within the system so that when the post becomes old it can be filed into a standard, theme-based menu system. Clicking on a post’s description, or tag (which is displayed below the post), will take you to a list of other posts by the same author on the blogging software’s system that use the same tag.

Linking is also an important aspect of blogging as it deepens the conversational nature of the blogosphere (see below) and its sense of immediacy. It also helps to facilitate retrieval and referencing of information on different blogs but some of these are not without inherent problems:

• The permalink is a permanent URL which is generated by the blogging system and is applied to a particular post. If the item is moved within the database, e.g. for archiving, the permalink stays the same. Crucially, if the post is renamed, or if the content is changed in any way, the does not guarantee the content of a post.

• Trackback (or pingback) allows a blogger (A) to notify another blogger (B) that they have referenced or commented on one of blogger B’s posts. When blog B receives notification from blog A that a trackback has been created, blog B’s system automatically creates a record of the permalink of the referring post. Trackback only works when it is enabled on both the referring and the referred blogs. Some bloggers deliberately disable trackback as it can be a route in for spammers.

• The blogroll is a list of links to other blogs that a particular blogger likes or finds useful. It is similar to a blog ‘bookmark’ or ‘favourites’ list. Blog software also facilitates syndication, in which information about the blog entries, for example, the headline, is made available to other software via RSS and, increasingly, Atom. This content is then
aggregated into feeds, and a variety of blog aggregators and specialist blog reading tools can make use of these feeds (see Table 1 for some key examples).

The large number of people engaged in blogging has given rise to its own term blogosphere – to express the sense of a whole ‘world’ of bloggers operating in their own environment. As technology has become more sophisticated, bloggers have begun to incorporate multimedia into their blogs and there are now photo-blogs, video blogs (vlogs), and, increasingly, bloggers can upload material directly from their mobile phones (mob-blogging). For more on the reasons why people blog, the style and manner of their blogging and the subject areas that are covered.
