We caught a brief glimpse of Technorati’s WTF, yesterday, when Rubel captured a screenshot before the service was pulled. Today, Technorati’s David Sifry makes the official announcement about the launch.
So what exactly is WTF?
When you see a top search with an orange flame next to it, it means at least one person from the community has written their view as to why that topic is hot – right now. The community is also invited to either write their own explanation or vote on the WTFs they view as most helpful. Based on a combination of number of votes and timeliness, the top WTFs by search topic appear on the top of the results page.
