Fair point (especially for super generic things like "#science" or similar) - that could sometimes be handled better. However sometimes there are multiple rooms discussing the same thing on the same network, so it's not always necessary to jump ship completely. But not sure I buy that the communities are that different. I would rather view them as different networks in IRC terms. You'll have a completely different set of people from one to the next, so how is it any different to joining a different network on IRC?
