For community outreach, I recommend the Google Fiber approach. I think the we should start a competition between communities and honor the communities with the highest demand with snapshots granting their chains a stake in what we're doing, much as Google selected cities and neighborhoods for Fiber internet service rollout. This solution is (relatively) low effort on our part compared to running and judging competitions, could generate massive publicity, and ends up with stake distribution to active communities who actually want it.
One (somewhat messy) idea for gauging the interest of the different communities would be to ask them to use vanitygen, and at a designated time see which chain has the greatest percentage of its total supply in addresses marked "BTS". Effectively this gives us advertising space in other blockchains and gets people talking and learning about bitshares, while selecting an interested community to recruit to join us by snapshot distribution, either to the entire chain, or specifically to the vanitygen marked interested parties within that chain.
