(particularly related to question/answer sites such as this)
Quite often people want to ask "How do I/you... ?"
Maybe to be less personal or to have a generic title, "How to... ?" is chosen instead. To me this feels quite jarring/incorrect (discussed here: Is a question beginning with "How to" grammatically correct?). Why is this wording so common?
"How does one... ?" might be more appropriate, but could be regarded as too formal or pompous. Is Is there another, better way to ask?
