Technology As Innovator

I admit that what kept me on Facebook for so long is its ability to host photos. I’m really happy how Photos and Photo upload work in Facebook.

The only thing I don’t like about it is that it auto-resizes photos to 604px width.

I don’t use MySpace, unfortunately.

The third most popular social networking site is Orkut, and I have some friends there.

I’ll just make a comparison on my most frequently used feature: Photo sharing.

Service	Quantity Limit	Capacity Limit	Resize	Allowed formats	Tagging
Facebook	Unlimited albums 60 photos per album	None	Width 604px	JPG, PNG, GIF	Yes, with better usability
Orkut	10,000 photos 100 photos per album	None	Width 800px	JPG, PNG, GIF	Yes

Intro

When I first heard of “Web 2.0″, my expectation was a new standard of World Wide Web. The usage of the term failed me, as Web 2.0 points me to what happen on the surface - user interaction and collaboration.

Web 2.0 roughly defined

Web 2.0 is not a new version of WWW. It refers to a phenomenal shift from centralized information authoring to a platform that enables end-users to interactively create, maintain and share contents.

Components

Mistakably Web 2.0 is used to describe relatively new forms of communication via the web:

• Weblog
• Social network
• Wiki
• wiki(RSS)
• Social bookmark

However, it coverage is much larger. Comparing to the definition, the following are also part of Web 2.0

• Instant Messaging
• Text chat
• Forum
• Real-time editors
• Search engines

This is not an exhaustive list though, as new trends continuously emerge at the time this entry is written.

Characteristics

• Open communication
• Information sharing and reuse
• Many-to-many authoring
• Publishing methods that requires less technical expertise
• User-centered
• Endless evolving. This is what “Beta” is for

Technology

Ajax was coined in February 2005, and has been widely equated to the technology that enables Web 2.0. In fact, features that Ajax has to offer had been initiated earlier. Microsoft Remote Scripting, which exploits Java Applet was a good start, then XMLhttpRequest flourished in Microsoft Exchange Server.

M$ did it at the first time, how did Ajax gain the fame? The answer might lie in its open nature. The Web community collaborated to develop, apply and reuse the technique. ‘Open’ and ‘community’ are the key traits of Web 2.0, it is no wonder why Ajax has become that popular.

Technically, Ajax is not a technology in itself, but a group of related technologies:

• XHTML
• CSS
• JavaScript
• XMLhttpRequest
• XML

My experience

My first experience with Ajax was July 2005 in a vbb forum. Although having been working with Microsoft Exchange Server for a long time, I couldn’t help a Wow. The wiki(usability) of the technology means very much to me as a web user. The sad reason is justified in the next section.

My first experience with Web 2.0-in-definition traced back to 2002, when I first used Yahoo! Messenger and Yahoo! Photos. Y!M opened up new horizons for me.

Pleasure

More than sharing and collaborating, Web 2.0 satisfies one dramatic desire of its users: ego affirmation. The virtual freedom of speech and the power of customization bring in the magic for laymen to lay their hands on creating and embracing their ‘I’ over the net by creating auxiliary identities.

Accept it or not, even ones who claim to pronounce what they want, or that they are wearing no mask are consumed by their own idealism, if not subconscious deluding.

Digital Divide

Vietnam International Internet connection bandwidth is so narrow it hurts.

Conclusion

Being abused, misunderstood, misused, Web 2.0 stands as an innovative evolution of Internet usage. While criticized to not being a deliberate advancement of technology, it completely revolutes the way users interact with the Web in the way it should have been, and proves the rationale of the rigid-free online business models. Web 2.0 enables collaboration, preserves and shares information and knowledge, brings business opportunities, enhances productivity, and encourages online practice of democracy.
