Which is the best online social network to find friends on? I have used MySpace for so long that i am ready to find another and now that I poked around online I see that there are over 30 different ones out there now and was wondering what everyone else is using to attract friends?

I like the look of Facebook and Bebo looks pretty cool but so does hi5 and orkut so not sure what which the best one to use would be that is not going to attract a bunch of spammers and has real local people on it I can actually meet! Please leave any bad experiences you may have had at some to if you want
