I have a new book coming out shortly on a topic that should really do well in terms of discussions, and I'd like to include an offer to visit my new site to offer interaction with me, and with other readers...or just those interested in the topic.

I'm trying to decide what would work best. I am familiar with Wordpress. Or I could use static pages for the main content of the site, and add in something like disqus, or I suppose I could go the bulletin board route.

Any ideas on what might be best if the goal is to encourage people to interact on the book topic, the book, and so on?

Any things I should take into account when making a choice of methods?
