I am now an active contributor to another blog called Bicycle to Work! In fact I made my first post tonight about my ride commute in the post titled: Oooo, did you smell that smell?
I took some videos of my ride that I will most likely post here. Editing them and putting it to music will take some time.
I was invited to contribute through a connection via LinkedIn, which is a professional social networking community geared towards making professional contacts in the hopes of finding new business, or finding a new job. Similarly, on Facebook there are quite a few Mountain Biking and Cycling groups or pages. I started one for CT NEMBA. There is another called iBike, as well as Cranfire.com and Ridefetish.com both have a presence there. I am sure there are others but I just haven't had time to explore any further.
If you are a bike commuter yourself, I would recommend joining LinkedIn, and find the group Bicycle to Work and ask to join and then you can blog your commuter stories.
