Thanks a lot for the feedback!
I agree with you, having to keep tabs with thousands of new services is annoying.
In that case though, you shouldn't have to worry about missing some users' feedback. That's why you have to register your project with FeatHub before people can give feedback (we temporarily enabled anonymous import to boostrap the service, but that won't last). This way, as a repo owner, you know you have enabled FeatHub.
Also, it's not implemented now, but we could imagine notifying owners on a regular basis. I suggested the improvement there: http://feathub.com/feathub/feathub/+8
