I'm wondering if it's in the spirit of the site or if my questions will get down-voted to oblivion if I were to answer my own questions as I post the question. My goal of doing so is to build some sort of public KB; stuff that I could reference in the future, share with co-workers and the world. But I read on another meta post about not asking and answering your own questions if they're trivial.

An example of the type of Q&A that I'm referring to would this post from earlier. In that example, I came across the problem of dnf wanting to remove a kernel that I wanted to keep. I quickly got the answer by asking in IRC, and thought to put it in stackexchange for my own reference and in case someone else came across it.

Also, does this type of Q&A help to increase your reputation?
