I honestly would've been fine just reusing most of last year's categories and replacing a few of the outdated ones with more current ones, but it seems like a lot of people want fewer categories. I have to confess that I don't entirely see the purpose of this; if you don't like a category there's nothing saying you have to vote in it. As for saying that people might not be bothered voting/nominating for all of them, well, that's life. People will probably have about two weeks for nominations, and I got enough nominations for all of the categories last time around that there weren't any problems going forward with the awards.
But, that said, I'm going to leave it up to the boards how many and what awards we have.
