Was just going to summize.com which was previously a 3rd party search through twits from people. And now it redirects to search.twitter.com!

And read the news in twitter blog that they have acquired summize and integrated that to their search.

There is an undeniable need to search, filter, and otherwise interact with the volumes of news and information being transmitted to Twitter every second. We will be adding search and its related features to the core offering of Twitter in the very near future. In the meantime, everyone is welcome to access search.twitter.com—there’s no need for a Twitter account.

Our Commitment
Overall service performance remains our first and foremost priority. Adding five extremely talented engineers to our team serves to further this goal. The addition of search to our existing API creates an opportunity for more diversity within projects developed on the Twitter platform. We will continue to support existing applications built on the Twitter API and look forward to innovative new approaches.

Was this a wise deal? As i see twitter down most of the times, and at least summize was good at that time to see what was discussed previously. Now that search also goes when twitter is down!

This is a sketch given by twitter of how search might be in twitter -
