Facebook and Twitter both. Two different things for different purposes, really like both. I used Facebook to keep up with friends and Twitter to keep current with my favorite topics.

Facebook

Facebook.....

I actually use all three, but I like Facebook the most.

Twitter has been very helpful as of late with Spridge's updates along his trip!

i use them both

I've basically done away with MySpace because of the amount of spam that is present, however, I use Facebook a great deal and I think Twitter can be great for updating races, unless your trying to "Tweet" between your heat and the 'B-main" like Shaq did during the halftime of NBA games Though for racing fans, it might be pretty cool to get updates on drivers on their changes their making throughout a show like having NASCAR team radio feeds

I use Twitter, mainly to keep up with what other race fans are doing. To me there is nothing more instant, also some of the people I follow are hilarious. There are a lot of drivers, photographers and fans. I have had Facebook and Myspace, a little to cumbersome and way more time consuming.
