There's a major problem with someone being made to give feedback when they really don't have much to say:

You'll get halfassed responses.

Seriously, I'd rather get someone who wants to give feedback not as often, but when they do really take the time to give solid responses over someone who doesn't really give a fuck and only gives it because it's required.

I see where you guys are coming from (especially as someone who constantly asks for feedback) but requiring it wouldn't really fix the problem. If you want tips to get better, it's better to get it from someone who wants to help.

At least, in my opinion.
