There are two kinds of people out there - those who get Twitter and those who don't.
It's easy for someone to grasp the usefulness of a social network like LinkedIn or Facebook but a lot of people have a problem understanding the value of frequent 140 character messages on Twitter.
So I asked Jason Therrien of Thunder::Tech about Twitter and he gives some good advice in this podcast.
Like you should only tweet with about the same frequency that you eat each day. 3-4 times. Listen to some more good ideas.
