As I check the criteria one more time, I see that I am supposed to comment on why I chose blogger---I found it easy to use (and if I can use it it is very 'user-friendly!) I also participated in a blog discussion in a great Education course I took at University of Victoria last year,(Alternative Texts). I came to prefer the blog discussion over the classroom discussion, because some students didn't contribute much in person, but had brilliant insights and stories that they felt more comfortable contributing to the blog. Not everyone likes speaking in front of a herd of their peers---same deal with Pro-D, btw.
Finally, I am struggling with getting the RSS feed to show up on my blog, so I'll just keep plugging away at that or call in some more tech help for one of my kids!
