Tantek Çelik has just announced the release of Technorati's Microformats Search! Tantek has been the pioneer and mastermind behind microformats. So far, the use of microformats was forward looking, like "One day there will be tools that search the web for microformats, and then all the hCards and hCalendars we're implementing will be useful." Well that day has finally come! Now you can search all the hCards, hEvents and hCalendar objects scattered around the web.
Also significant is the announcement of Pingerati, a ping service to announce the existance of microformats on pages Technorati isn't already indexing with rss (ie. an About page). Yet another useful tool in the microformats toolbelt.
Congratulations, Tantek, and thanks for such a great tool!
