It's like Apple and removing the power button/switch from the iPod. For most people it's "simplified" and they like it. But the people who care really care.
I'm already doing double-opt-in for the mailing list. It's saying at each point what's happening, and at each point I lose a percentage of people who started. It's a balancing act between pissing off people who just want it simple, and pissing off people who don't want to be tricked into signing up for something they don't want.
