The newsletter idea is appealing because I would know how many people have signed up for the weekly issues. I could also add news about contests, book launches, etc. The disadvantage, is that no one would be able to make comments. However, as I sit at my laptop and write this blog post, I realize I could send the readers to my website and have them make comments on my forum. Hmm, that could work, too.
What do you think? What have you done to help promote your first book?
