- Blog. The blog format offers a clean presentation for a mix of text and images. It provides some interesting statistics, but it doesn't lend itself well to feedback, I suspect because it may require a "captcha" in order to post a comment.
- Forums. I've been a long-time and active member on the WAMP forum. I recently joined the DragonPainting forum as well. Forums offer a nice structure for organizing discussions. They offer tools for following discussions of interest while ignoring others. However, it seems there are only about a dozen really active participants on a forum at any given time. Comments are hit-or-miss, but there are generally enough to keep me going.
- Social media. I just joined some Communities on Google+, and I'm experimenting with posting stuff there. I chose Google+ over Facebook, because I can more easily post photos from my Picasa albums onto Google+. Plus, I've always preferred Google+ over Facebook, in terms of presentation, intuitive ease-of-use, and privacy control. The feedback for posts is excellent. Participants can leave a quick +1, or they can engage in dialogue. The format is real-time sequential, though, which doesn't lend itself to organizing lengthier topics for discussion.
So give it a try! Let me know what your preferred posting medium is. Or remark on something about the blog that you haven't had a good chance to say before -- about painting, gaming, specific projects, events, whatever. Hope to hear from you!
