As I added a new profile picture on my Facebook account, suddenly several girls (friends of friends) started adding me. They didn't send any message, they just added me and, to the few I asked before accepting, they said they liked my style.

Where to go from there since they are obviously showing interest (even though with no follow up)? I should add that I don't live nowhere close to those people, so it has to be mostly online steps at least at first.
