Don't be silly. Even if FB disappeared tomorrow, "that crowd" isn't going to come to HN, just like they're not going to suddenly develop an interest in, say, electronics and start hanging out on message forums where people talk about how to design PCBs, or an interest in, say, astrophysics, and start hanging out on message forums where people talk about gravity wave detection. No matter what happens to FB, you're safe here.
