It's becoming a phenomenon in and of itself, I happened to get in on the first wave and thus my site is attracting a lot of attention from people who are searching for information. It's been great because it's allowed me to start discussions and in fact the site has almost double the comments then it does posts by me as people are asking questions and giving feedback.
If you're talking to anyone about the subject on any other sites, be sure to point them to my blog at
www.solegoal.com because I'm setting it up to be a bit of an information portal to help people interested in the subject.
