Leverage your use of Facebook, create a list within your friends of those who have 1000+ friends each. Those are your "leverage" list, whom have the most exposure to more people on facebook. A post on a friend with 1000+ friends gives you exposure to all of their friends as well with the (Friend has a new wall post) etc.

No spam, no links to your site, just comment on their profile, their new photo, their videos, their websites, etc. Befriending, not spamming.

Listen to Brian Campbell's 7-LeveragingPopularFriendsFriends.mp3 from the audiobooks you downloaded from me on day 9 of my "30 days to success" before going to Facebook to give you that extra incentive.
