Summary: Isn't Twitter mostly nonsense? No. According to the latest research, not yet publicly released from Greentarget, in-house counsel use of Twitter has almost doubled over the last year. Just think, over half a billion people are on Twitter, and it isn't because Twitter is trendy, but because it is useful.
Twitter is an incredible tool to find information because it is an OPEN network. It doesn't matter who you know, Twitter is all about the quality of what you say. It doesn't matter what school you went to or the company or firm you work at. Twitter can help anybody make a name for themselves.
