This isn't even a question. Miscellaneous has been suggested again and it won't work.
Yes, this proposal won't ever work, but for the sake of its creator it's probably worth explaining this with a more constructive tone.
Stack Exchange sites are built around their community of experts on one particular topic. This is how the high quality of the questions and answers here are maintained. What "expert" means is different on each site, but every site is, at least in principle, targeting some group of experts.
The problem with "miscellaneous", "general knowledge", "everything else", and whatever other variations have been proposed is that there are no experts on these topics. What would an expert on miscellaneous knowledge be? Someone who just knows a lot of basic information about almost everything? No one like that exists. The end result is destined to be that such a site is filled with low quality questions and answers by people who mostly don't really know what they're talking about.
If that's the experience you want, there's already a site for that. However, SE sites are different. They need to be more specific about their topic to maintain high quality content and an expert community. That's why no site like this will ever fit the SE model of Q&A.
