I'd like to see added to the frontpage that people should vote ideas based on whether they should or should not be implemented.

At the moment, I have noticed there is a trend of people voting against ideas, not because its a bad idea, but because they think there are other priorities. In fact, thats why almost every idea except a select few are +1. Even posts to fix grammer issues on brainstorm are getting voted down.

It should be emphasised:
+1 for ideas you would like to see implemented
-1 for ideas you don't want to see at all.

Because at the moment the reason so many things are -1 is because people think other ideas are more important at this time. I think our only purpose is meant to be sorting the crappy ideas from the good ones, and let the ubuntu team prioritise them.
