In the case of all the social media, and with any type of lead generation or list building, you want to focus your attention on actually helping people. If you focus on helping people in your marketplace first, they'll be much more responsive when you ask them to give their name and email address in exchange for helping them.
MySpace has the same basic premise as facebook: set up a profile; connect it to people who are interested in the same things you are. Some people say, "MySpace is dying," but MySpace is still insanely large, so don't abandon the ship on MySpace. If it's dying, all that means is that there's less competition for you to go in and get traffic and leads from MySpace. So if you're not using MySpace.com, definitely go for it.
PPC is another way to build your list. Google Pay Per Click, Bing, Excite, and even Facebook now have PPC advertising. Pay-per-click advertising is really powerful. It's a way of paying to get traffic to your squeeze page, to your opt in page or to get people to join your list. These are people coming to you wanting more information from you on X, Y, Z topic.
