Great Idea
We do a lot of brainstorming sessions at our company, but so far it has never crossed my mind that we can write the author of an idea. We always just put them altogether and went from there.
What you're saying makes complete sense because anybody who gets attribution because his or her idea was chosen will definitely feel better about themselves and they will be more motivated to work on the project. On the other hand if you pick an idea and you don't offer any kind of recognition to the person who thought of it, you risk alienating that person.
