make a determination, on if this is something that will be done, won't be done, or maybe will be done if it gets more votes.
If I know for sure something will never be done, I decline it right away. You can see this in many ideas if you search.
If something is completed, I mark it as completed (unless I missed something, in which case let me know).
Everything that remains is in the final two categories: on the "accepted" list, or on the "maybe" list. I prefer not to reveal which are which, since if I revealed something was on the accepted list it would just cause everyone to move their moves off of it and onto something on the maybe list. Or, at the very least, they'd be less likely to vote on an accepted item since they'd have more influence by voting on a maybe one.
This would skew the results and make them harder to interpret what people really want.
