What is your favorite social networking site?

facebook even thought they have had some privacy issues

I use facebook. I've always been very cautious as to what information i put on there with the whole privacy problem.

Right now I am spending most of my time on FaceBook. That being said, there current Newsfeed BLOWS CHUNKS and the current process for setting up your own special feeds BLOWS CHUNKS, so I may be looking elsewhere SOON! The privacy issues haven't bothered me like they have with others, although I guess they should, but I've always assumed that once people get that information that they will eventually abouse it and have protected myself accordingly.

Twitter beats them all HANDS DOWN! then it would be facebook

My favorite social networking site is Facebook :)

I Use to use Myspace but not im hooked on Facebook.

Gotta be Facebook. It's such a social networking giant that you're almost forced to use it...even if you're not that big of a fan.

Twitter because it is an original idea that has not been done before. Facebook is just another myspace, which is email with stuff piled on.

facebook, since all my friends use it and it is a really good way to keep in communication with everyone

Twitter. Without Twitter, I wouldn't have been able to connect with so many fellow space geeks and, amazingly, be among 99 other ordinary folks who had the first opportunity to see a Space Shuttle launch from the press site just 3 miles from the launchpad back in November 2009. http://www.opennasa.com/2009/11/16/its-better-in-person/

I also rely on Twitter search to keep up-to-date on topics and issues that interest me. I can dip in and out of the tweetstream as my interest and time permits, making it a perfect news aggregator or, at least, "buzz aggregator" for me. It helps me know what I might be interested in delving deeper into.
