Going to agree with the dudes who have already answered and say that sometimes, questions are just hard to answer. Oftentimes, I'll click on a question and start reading, then realize I have nothing to say about it/don't really have any advice. I guess I could leave a comment on every question like that saying "Geez, I don't know, sorry! Good luck anyway!" but that doesn't really help the asker.
Shamus, to increase your answers make sure the title is eye catching. Use proper grammar and spelling. Also, make sure that the question itself is interesting...try to not ask questions that have been asked before. Also, make sure to provide enough detail but try not to ask a question that entails multiple paragraphs. Hope this helps!
