Chris, I really enjoyed your thoughts and reflections on Wikity. I haven’t really used it for a while. In some ways it was a part of my first tinkering with the idea of a commonplace book. I eventually brought my posts there into my ‘collect’ blog.
I really like your idea about a plugin and would definitely be up for that. It reminds me of what Alan LevineAlan Levine has done with the Splots Writer plugin. This is also how EdublogsEdublogs have built wikis their version of WordPress.
