I wish the Android market would provide some ability for the developer to respond to comments. Something like the facility that TripAdvisor has where a hotel owner can respond to comments.

Right now the top comment on +aCal says "Please delete this comment". Like I can. I can't even ask for Google to delete it. I can't even reply and say that I can't delete it. That all kind of sucks not just for my own user experience, but for my customers user experience. Many of their complaints are solvable if only I could communicate with these people!
