Web 2.0 Validator
If you ask people “What’s Web 2.0?” Different people will give you different answers. In my mind, central to Web 2.0 is Ajax and semantic markups (i.e., microformats, RDF, or OWL).
Question: How do I know if my website is Web 2.0?
Answer: Do one of the following:
- Read what Tim O’Reilly has described — a laundry of list of Web 2.0 characteristics. Evaluate whether the technology that backs you site meets what he has described.
- If reading is too much for you, use Web 2.0 Validator — an automated web tool that scores your site based on a set of Web 2.0 characteristics. Note that the tool does pay attention to whether a site (a) uses Semantic Markups, (b) mentions RDF and the Semantic Web.
Here is how my website scored:
The score for http://harry.hchen1.com is 11 out of 43

[...] Harry Chen blogs about Web 2.0 Validator, an automated web tool that determines how 2.0ish your Web site is based on a set of Web 2.0 characteristics. While Harry reports that his site only scored 11, it now scores 31! No, I don’t think he’s just been studying for the test so he could retake it. It appears due to Harry’s post on Web 2.0 Validator. Apparently, talking about Web 2.0 Validator makes your site seem very Web 2.0 to Web 2.0 Validator. Or maybe this is related to Russell’s paradox, somehow. [...]

[...] I think this is an interesting project. First, it provides a unified and shared information space for people to discover and discuss personal finance and investment news. Second, collaborative editorial control can help to filter out insignificant news and blogs posts. Fully automated blog aggregation sites such as the Money Blog Network are often cluttered with posts. As bloggers flood the site with tons of new posts everyday, it becomes harder for the readers to find useful news that are worthy of reading. Finally, it’s web 2.0! [...]
