I'm sure many of my fellow Sifters visit other sites on a regular basis. I for one have 3 other sites that are favourites of mine. This thread is about discovering the other communities that our Sift buddies are using, and finding a new interesting community. Now, about my sites

Kongregate: a flash-gamer's heaven. Over 3000 games and growing with tons of challenges and chat rooms. Currently in Time Magazine's Top Ten Websites List for 2008.

FFR: Flash Flash Revolution. Like DDR for your keyboard. More fun than it sounds and a steep difficulty level (tangent: my school bud is ranked in the top 1000 worldwide so he's in a tournament to win 2000 dollars at his group level.).

Homestar Runner! No description needed.
