Consider some users with high reputation but without any question. IMHO, I think every people in the world has problem to be asked to others.
So the questions are
How do you ask a question?, I've only seen an answer box.
i can't speak for the gentlemen named in this question, but i can see some definite benefits to participating in the community without asking (m/any) questions.
an interest in increasing the skill and knowledge of tex users, which in turn helps to ensure the continued use of tex, which much of the world thinks must be obsolete because the underlying software has been essentially "frozen" since 1984.
learning new ways of looking at various problems; particularly if a person is involved in writing packages or documentation, that person can't predict all the myriad ways instructions can be misinterpreted, no matter how paranoid s/he may be on the subject. input from a varied (and in this case, volunteer) user base helps one to improve materials intended for "public" use.
the satisfaction of having been helpful and even useful.
Speaking of myself, a while ago I realised that I have been a member of the site for almost two years without asking a single question, so for the next issue I had, I decided to ask a question after a reasonable attempt to finding an answer.
But generally, I’m not used to asking questions, I just try to figure the answers myself, this is how I usually work TeX.SE or not. So why do I participate in this site? I learn a lot by reading people answers (even if I’m not immediately interested in issue, as there is a good chance I’ll need it at some point, and then I’ll know where to look), and if I can help people with things I know, why not.
