Don't know if anyone's mentioned these:
Obviously we should get every page on facebook about Ron involved such as "New Hampshire for Ron Paul" and so on times at least 50.
Groups, forums, markets to target be it on facebook or websites:
C4L and YAL
Free state project members, I believe they have their own forum.
economic groups like the forums on the LVM academy website
Reason magazine has a ton of people on facebook and by clicking on a few commenters under their posts i've noticed that most don't have anything in common with me such as attending BTO, I'm guessing their are a lot of libertarians that subscribe to reason but don't have the RP contacts on facebook so they are oblivious, if we can find a way to contact that audience somehow....
MEETUP groups, particularly tea party ones if added up across all the states you're talking about a large number of people, it's worth joining them to post about BTO.
Just some thoughts...
