This is somewhat related to my tendency, when assessing something new, to find out what its harshest critics have to say. If, assuming their facts to be true (for the sake of argument), their criticisms are still pretty wimpy, I take that as a pretty good accidental endorsement of the original idea. To put it more bluntly, if people have to desperately fish for stupid things to bitch about, the idea is probably a pretty good one.
