I don't really mind criticism if it's from somebody who's been there and done it, or even has a small amount of experience in the area. The problem is that most of the time it seems that the early commenters who speak with so much certainty about the prospects for success about what somebody else is trying to build have zero experience in the given field and whose opinions are basically worthless. I've seen this more here than anywhere else. A specific theme I've seen come up time and time again is "X won't work because EVERYONE knows you can accomplish the same goal by doing A, B, C, and D." It's "let me look at this product and think of reasons why it could potentially fail" without reflecting on whether or not they really know what they are talking about. For example if you are shooting down a job board for older developers because you've tried to launch a job board and failed and know the specific challenges involved and see them present in that product, go ahead and shoot it down- your advice is likely very insightful and helpful. However if all you've done is sit at home and tinker around building "side projects" while occasionally commenting on discussion forums and haven't publicly launched a similar product, your opinion probably sucks.
