Did you know if you search Twitter with a hash tag (#) in front of your search term you will get a stream of results around that term. Try using a desktop Twitter client like Tweet Deck for the best results.

Use it to track your interests or for research. Current trending topics would be seen like this: #Obama or #Inag09. I’ve found it to be one of the more useful tools available – especially if you want to follow events like MIDEM, the annual music industry convention currently on in Cannes, France or get virtualy involved with Amplified #amp09, the WebTV conference currently on at the ICA in London.
