I am not asking for myself, I am asking for someone else who will likely not read this question because he is too busy reading his email, but I am sure that this question will be of a lot of value to others.
The poor guy has the problem that his development project got quite a bit more attention during development than he liked. Now he gets bombarded with emails full of bad suggestions and useless bug reports. Reading through all these emails takes him several hours of development time each day. However, not reading it is not an option either as it would mean that he could miss some emails which are actually important, like mails from potential project members, useful bug reports or press and business contacts.
He recently called it the biggest problem for the development of his project in a 20 minute video (you don't need to watch this rant entirely. The blog post linked in the first sentence of this question summarizes it very well)
How can a game developer canalize and filter their feedback stream to improve the signal-to-noise ratio?
