One more thing about the "chunks of ideas", maybe we should also limit the number of solutions a user can post?

There are some very prolific users that keep adding a new post for every word that comes in their mind, instead of editing an older post that is on the same wave length...

I haven't yet seen 2 ideas in one brainstorm form the same poster that are so different from each other that they can't be expressed in the same solution.
As for users that have more than one idea on how to implement a specific function, NO! Weigh their ups and downs and post the most relevant one - before coming to brainstorm, know exactly what you want.

My brainstorming about keeping brainstorm brainy is now complete
