Many software developers give an opportunity to their users to submit ideas for new features. Things work the same way within the WordPress community. ManageWP recently offered a whopping $1,000 to the winner of best idea for their plugin. Clearly, users are some of the best sources for gathering feedback about your product and how it can improve.
Thankfully, we can now use a very similar system on WordPress thanks to the Avia Feedback Box plugin by Kriesi.
