Buried by the news this week of Twitter adding search was another Twitter feature release: invite friends.

The new invite friends option in Twitter allows users to invite friends by adding an email address or by importing Gmail contacts.

Twitter investor Fred Wilson writes that to date “Twitter has made it nearly impossible to find friends on Twitter. That’s a very big shortcoming of an inherently social service. It sort of makes me wonder how Twitter got any users at all.” According to Wilson the new feature overcomes that problem and that he “just tried it out and it worked great for me.”
