Along those same lines - I started working on my first iPhone app and added a simple feedback button to gather user feedback. Then it occurred to me that this feedback mechanism itself can be offered as a service. Kind of like a Get Satisfaction or UserVoice for mobile apps.

Anyone think this would be useful? Would anyone actually pay for something like that? It'd probably have a lightweight library for the various platforms, and any app can integrate the feedback button with just a couple lines and an include. Initially it'd just gather raw feedback - probably with a interface that helps let the user know what the form is for - and later on adding more community-based feedback features that other web-based feedback services provide.

I know there are a few companies that offer mobile feedback integration, but none that are very active or solely focused on mobile.

What do y'all think?
