Not sure if this is done somewhere already, but there are *so* many suggestions here, many with a significant number of comments and votes. It's very frustrating to see items that NO ONE from RTM even responds to. (What, are you... Google? LOL)

Although I know you can't acknowledge everything, it would be nice to at least see which you plan on implementing and what the priority is for you... Even if it's going to be 1, 2, 3 years down the line.

I think it would go a long way to showing you respect your users and their comments.
