MicroPlaza, the next Search Engine for Twitter

After a short read of an article about the Eric Smith’s vision of Twitter (http://www.businessinsider.com/google-ceo-twitter-a-poor-mans-email-system-2009-3), I’m wondering if MicroPlaza is not the NextGen (cool word) Search Engine for Twitter. Why ? Pros:

• They already are indexing the whole Twittersphere. (Not the whole, in fact, just the links)
• It’s hype
• They have knowledges in content indexing

Cons:

• Twitter is not used by everybody, maybe the system have to scan other systems
• Is the twitter content worth ?
• Yet another specific search engine

Anyway, wait and see :-) [Edit:] And they did it now :) http://microplaza.com/search
