It's a bitcoin forum, we have no interest in making altcoin forums. Alt currencies board was made as an alternative to just deleting them. I'd be okay with just removing it, at this point it's just seeing who can spam the most giveaways or whatever in order to pump their coin.
This. There were no alt coins when the forums were created, so thats pretty good reason for not having the boards specific. It is a rather simple system though, this is a Bitcoin forum (Bitcointalk) the Altcoin section is as Badbear said, a place to place the altcoin topics so that they don't disrupt bitcoin conversation that isn't the trash can.
A very large portion of Bitcoin users don't like Alt Coins as it is, so having an Alt Coin section isn't a bad compromise. It would be preferable if we could get some general subforums in the Alt Coin section, however what we have is better than nothing.
The goal of alt coin section is to allow a bit of alt coin conversation as long as it stays in its own section. It is preferable that each coin establishes its own forums for full range.
