The best part about Valve Software's over-the-Internet purchasing system, Steam, is that it saves you from having to visit video game stores. There are many things to like about gaming as a hobby, but I'm not sure that other gamers are necessarily one of them.
Which you can say about just about any hobby, really. If it weren't for the fact that I like to physically try instruments before I buy them, I'd never go into Guitar Center ever again. There are far too many musicians there.
On the other hand, I wouldn't ever say "I can't stand the bookstore--I keep running into other readers." Perhaps because it's traditional to be quieter around books. The library stigma is beaten into us as children, and the fact that literature is an entirely visual medium requires more concentration, but also presents fewer distractions. There are no doubt really annoying people at the bookstore (probably in the literary fiction and Business How-To sections), but they're not talking.
