I sometimes go back and forth on whether or not I think these questions are useful for the site. However, I fear that covering off such basics could lead the site to be thought of as quite simplistic - comparable to Yahoo Answers / Quora in just allowing all sorts of questions.
Stack Exchange sites expect users to have done some research into their problem before posting a question. Taking the help centre article on how to ask a good question:
Have you thoroughly searched for an answer before asking your question? Sharing your research helps everyone. Tell us what you found and why it didn’t meet your needs. This demonstrates that you’ve taken the time to try to help yourself, it saves us from reiterating obvious answers, and above all, it helps you get a more specific and relevant answer!
There are plenty of Usability 101 sites out there already, Stack Exchange shouldn't be 'one of those sites with lots of UX stuff' it should be a repository for specific, unique, useful UX questions and solutions. It's a site for experts, not for early education.
The same way that Stack Overflow isn't thought of as a site for educating people on the basics of programming, or physics.stackexchange isn't for beginners in physics, they are sites for the professional - in a sense, they are professional tools. That means the quality of questions posed are generally high, and as a result they are highly respected sites.
Quality of users, questions and answers is more important that volume. Sure, 101 questions may bring more people to the site, but that doesn't necessarily equate to higher quality (and may even be detrimental in the long run).
