Maybe this is a bold (visual pun intended) idea...and maybe this idea should be posted somewhere else (which I have no clue where)...but here it goes:
Why don't make a separate website, linked with the electronics one, just for surveys? Reason: Opinion based questions are pretty much banned (for many good reasons), but still there are lots of people interested in asking them and answering them....so why don't make a survey kind of website linked to the electrical engineering website, but still separate? This way all the "stack style" Q&A websites can have a side survey website, just dedicated to this kind of questions.
The cool thing about it is that opinion based Q&A (which I am calling "survey") can benefit a lot from the way stackexchange behaves. People will post their opinion, as answers, and if someone agrees, he just vote's it up...the opinion that the majority likes will "bubble up" and be placed on the top.
Yes, opinion based questions can be horrible, most of the times there is no "right answer" and things go as an eternal discussion and this clots the website...and that's precisely why I am suggesting making it in a separate website, so who goes there knows what he will find.
Discussion is good, it promotes general thinking and sharing of opinions which bring new ideas. If we are a hub of knowledge in electronics IMHO we should give people a way to "document" this kind of discussions as well. I have learned a lot about software design listening to eternal discussions of which framework is best, the same as I learned a lot about PICs and AVRs just by listening to countless discussions on which is better...all this discussions have no end...but I learned A LOT from them still!
Also having a "merge" tool where two people can agree to merge their answers will be great (for all the websites styles)...lot's of time I can see someone who just add 2 cents to the other answer, but they are good 2 cents and they usually are not in the top.
So if someone could forward this idea to the creators of stackexchange, it will be most welcome...I would ask what you think about this, but then it will be a survey :D
