if you find yourself wanting to have some fun with other fans, this would be the place to visit on livejournal! whedonland, a joss whedon fan community, is a place revolving around different tasks/contest/activities where fans are placed on one of four teams [buffy, angel, firefly, dollhouse] to compete for points.
it's interactive and looks to be a lot of fun with not just challenges but also discussions and fun comptetition. i've joined the dollhouse team because that show just doesn't get enough love. but you can join one of the other teams and i won't hold it against you!
