We are having an "interesting" chat in the Super User Root Access chat room, (Start from about here)
I Personally think that Why are the 8 bits per byte is a very good question and represents the sort of content I want to see on Super User.
This same FAQ rule is on Stack Overflow and I am guessing other SE sites. Whilst I feel that there will be a few bad questions, there is no reason people can not use their close votes on those ocassions, but I feel strongly that there are MANY good answers across the SE sites that are not actually directly about individual problems.
To add to this, I just mean to say, there are many on topic questions which are good fits to the sites, just not about actual problems - I am sure many can be phrased to look like a problem, but I just don't see why it should be necessary.
And another edit-- To clear up a little confusion, this is not a "Why was xxx closed" rant, I know why it was closed and I do agree that it should be under the FAQ rules, I just feel like there are many other questions that also fall under this scope and I would personally like them to be allowed.
Right now, we have rules that are up for interpretation. Some questions are allowed and active but clearly are breaking them, Where as we should have much stricter rules with no "wiggle room".
As a compromise, possibly just have an exception clause for "interesting questions of merit", I do not want to see "Why are 95% of power cables black", but I am interested in this in the same way as others were interested in A/B drives!.
