Leo Laporte and TWIT are suing Twitter for breach of a contract. It seems that TWIT, the audio and video podcast success story, was the first to go to market with the brand TWiT.

While a guest on Leo Laporte's net@night podcast, the two reached a gentlemen's agreement to stay out of each others' business. Now it seems that this agreement was breached, as Twitter moves full steam into the video streaming world. Let's check out this lawsuit of TWiT vs Twitter.
