I was considering something closer to "bait" and less like the "hook" you're describing. For example, I just finished writing program today that you can play chess on, but it requires another person to play against. However, I wish to implement a Genetic Algorithm/Artificial Neural Network that learns how to play chess and win as time progressed. Because I don't want to play chess against a (literally) dumb AI a thousand times, I plan to crowdsource it and allow thousands of other people to do that job for me. If the Guild had something like that, it could begin to draw people in, since they would be talking about it. "Hey, did you hear about this site called 'RoleplayerGuild?' They have this really cool AI Chess thing that gets smarter the more it plays against people; it even beat me once!" That begins to direct traffic to RPG so people can see this feature (and possibly many others), while a percentage of that "sticks," and stays for the hooks you mentioned.
