Jason brings up a very good point. Especially the first part (where people tend to dislike tough criticisms) resonated very well with me because - my startup, StartUpLift.com - specializes in providing crowdsourced feedback to startups. One of the features that we offer to startups is that they can reject any feedback / feedback provider at no cost to them. It's interesting to note that more than 65% of the rejection happens when when they get some sort of negative feedback, which in fact is a disguised constructive criticism.
