The blog being published by one of our partners is, from my viewpoint, a success. Blogger has done well by him, providing a forum, which seems to be building momentum.
Sometimes "simple" is an excellent thing, and Blogger seems to make it simple.
Adding an attachment is a little more difficult for some users, but taking one step at a time, these capabilities together provide the power to publish!
