Facebook and Twitter. Focus on those two.... there are so many other social network sites out there but they are not as big.
I perosnally prefer Facebook as its more popular than other social networking sites. Though twitter is equally popular but its still very new and has less number members too.
They're oversaturated. So becareful. People on facebook know a scam and a pitch so it's harder to try to sell them things, twitter users are a little naive so they'll click links but again conversions aren't as good as getting something to the front of say delicious or something.
