Summize is a fastest Twitter search engine that I ever know. I find it especially useful when I want to track the buzz of a certain event or topic among all the Twitter users in nearly “real time.” After I keyed into some keywords into the search box for what I am looking for, Summize searched all the real-time conversations on Twitter and came back with the results, it showed “iphone” still one of the top topics among all the Twitter users, and I even see some tweets was indexed less than a minute.

Summize is a great service that compliment the Twitter Public Timeline, by providing a control mechanism on what you really want to read on Twitter. Will it be better to search Summize for the Twitter’s conversations when Twitter is down intermittently? Probably it is. By the way, if you like Summize, I think you’ll also like their soon-to-be launched Realtime Sentiment, Summize’s another project that currently still in labs.
