It is really motivating participating in a Challenge. It forces you to do something, anything, just to have something to post on a given day. I posted for the first time on WOYWW last week and I received more traffic then on any other posting. The comments were positive and very supportive. Which couldn't have come at a better time, I so needed the reinforcing. But I also found some great sites, more ideas and some new techniques to try. But most of all I found more friends. I'm loven this blogosphere.
