Is there a way use some sort of third party forum moderation to cut through this problem? Then you could go on in whatever way you are comfortable, your forums could coninue to buzz and anyone that's up to no good would hit a brick wall (or get a call from their local authorities, as appropriate). It's just a thought.
Kathy, the content you have graciously shared with us every once in a while is both inspiring and entertaining. And a blog is the perfect medium for this. A lot of the content is about your style and creative personality. Thus, I would rule out the community-based ideas. I would probably only read your stuff anyway.
In doing this blog and thinking about this stuff, have you ever had any ideas for what kinds of tools (software, that is) that people could use to do things like share creative ideas in groups, create customer community, etc. etc.?
