I think it's because BaB deals with books and the like, so to make things less confusing they put the title (e.g.: Warriors Roleplay Thunderclan, Marauders RP 2, etc.). If we were to just start each thing out with, "I like the..." or, "These books are..." like we do on, say, DtE of CaC, it'd make things more difficult to follow.

Still, it would be nice if we could get them in other places, too. We sometimes try to put in our own topic titles, but if they're long, they don't always fit. If they're short, they often get extra letters put after them (such as: D@nbs&k). That can get annoying.
