I found setting up my blog pretty easy. I have a blog for my library website at school and it all pretty much worked the same way.
I enjoyed creating the avatar. I reminds me of setting up a Mii on my kid's Wii. The hardest part about that was uploading it. I sought out my sister (our family tech-guru) and she showed me how to save as a jpeg and upload it that way.
I have looked at a few other blogs. I have not yet posted any comments or questions.
