Here is a question [sorta on topic in this thread]... awhile ago I wrote a marketing tool that recommends social news sites based on content you provide it. The idea was to help people market stuff better by finding communities that want it. I ran into a problem coming up with a critical mass of sites though. I have about 70 before I got tired of looking.

What would you think of something like this applied to slinkset sites? Anytime a Slinkset site is created this directory could update itself and serve as a way for new people to find these niche communities.

My original prototype is at http://kindling.dashnine.org (I posted it to HN awhile ago)
