Right, I'm not saying the guys who run StackOverflow need to allow me and my opinion surveys on StackOverlfow... But the StackExchange platform allowed them to create Programmers.StackExchange.com, where opinion polls are welcome. EDIT: slightly more welcome, sometimes, maybe. If they had figured that out sooner, and had migrated questions from StackOverflow, they could have done a much better job at engaging users. Saying "your question is closed as off-topic" is totally different from "your question has been migrated". I commend them for the second, and I condemn them for the first.
