hmm lets see if i can convince you then ~
first of all PU differs from every other OM because its usage based, like every official tier (well from ou to nu). pu also has one of the biggest threads in the forum, as well as active projects such as tourneys, keirans CCAT thread, and really, in #neverused we like to discuss pu a lot as well. i mean sure there's nothing against talking about it in #othermetas, but we've had some good discussion going on in #pu (combusken :O) and its a pretty social chan as well.
that said im sorry i posted about it, i never read that part about no splinterchans
