I want to use this at Edcamp Hershey! Bright colors and fun animations. No account necessary, just type in the keyword or hashtag you want it to search for.
This will give you a chance to search trending topics by #hashtag on Twitter without having to log in to an actual Twitter account. This could be beneficial in a classroom to remove some of the personal connection while still providing the students with live media. Current events are simply summarized and given personal perspective on Twitter, without the students seeing a random comment about what one of my friends is having for lunch.
