at this point the biggest benefit to becoming a fan is if a seller decides to go into stealth mode. Their listings won't show up in the regular sections, and you can only get to their page by using the direct URL (which you have if you are a fan).I have been bugging SR to open it up a bit and let us vendors be able to do more with the Fan option, like fans-only sales and stuff like that. I would be all over that :)
