I visit a few forums that are extremely slow. I recommend it. There's a stronger local culture to these places, since you can get to know individual posters, whether by username or style. There's more room for slow, drawn-out conversations that can take place over days or weeks, which you can drop into and out of without losing the thread, and you have a chance to engage in one-on-one conversation with individuals without having to resort to DMs or a chat system.

Everyone on that designer web forum smells their own farts. It's not local culture it's seclusion.
