Nowaday, if we go to http://search.twitter.com, it will redirect to http://twitter.com/#!/search-home (the template is look like Google, with no logo). I miss the old http://search.twitter.com things; simple, fast, and with more features (such as feed) What's happened with the old search.twitter.com ???
This the latest update of twitter search, can't turn back to the old search interface. If you want to search high targeted followers, click “Advance Search"
You can do searches from the new Twitter homepage now and the search.twitter.com links redirect to that. Personally I don't like the new twitter homepage at all.
