Hi this is based on something that Twitter released last year, but has never gotten wider adoption. I had some time to put this together while traveling this week. Now with the ability of opening your Direct Message inbox to everyone (not just the people you follow) you will get a clear call to action button for your tweet. Some people like http://www.twitter.com/nodejsdublin use a tweet like this pinned to their profile and it works quite well.
