From your comment, it seems like your real question is:
Why are some simple questions 'hot' while other more interesting, or involved questions get nothing?
Certain questions just seem to "hit a chord" with the community, by receiving a lot of clicks. A few general observations:
Questions which only apply to a few users, and which most people don't care about, tend not to get very many clicks, except by people who either have the same problem, or are trying to help answer the question.
Questions which ask stuff that many people are likely "to have wondered about", but they don't know the answer off the top of their heads, tend to get a lot of clicks, a lot of answers, and a lot of upvotes. This is not so much about the simplicity or complexity of the question, but about how many people are familiar with the subject matter in some way.
The question you answered was about mice, so I'm sure lots of people know what a mouse is. If you asked a question about, say, iText or Adobe Acrobat Pro, you'd have a much more niche audience -- people who don't use those tools do not care, so they don't click on it or vote.
Unfortunately, this is how it works. The quality of the question/answer is less important than what people consider to be "interesting" and "relevant to their own edification" in terms of # of clicks.
