I signed up for Twitter awhile ago, and would post a tweet once a month, because I could not figure out what to use it for. So between signing up and now, I've had a love hate relation with it.
Recently, Vincent Wright, the head of one of the networking groups I'm associated with, posted a message to all of the members with a great way to use Twitter, and invited us all to post our Twitter profiles to the group.
Since then, I've learned what a valuable tool Twitter is, and since I have a great iPhone App - TwitterFon, I can check and post tweets throughout the day.
I invite you all to join, and follow me.
