I've become a fan of Facebook. But if Facebook raises concerns about the rights to the stuff you post there (found via Instapundit), then Facebook may find out how fast a social network can become moribund. I'd like to see something a friend of mine suggested, a Lolita debate about Facebook's merits (e.g., does it encourage or discourage social interaction, on balance?).
On a more-or-less unrelated point, I'd also like to see a debate on whether computers will become smarter than humans (in our lifetime or in this century, say, to leave the unfathomable far future out of it).
