I understand what your saying, but like everyone said sometimes it's hard to reply when you are on a time limit. If it is an urgent situation, most people will reply right away if they have any advice.

Also, sometimes I don't reply (not to you, by any means, no one specific) because sometimes people ask questions that they already know the answer to. When you try to be helpful they won't just take the advice and say thank you, they will argue with why it won't work. That bothers me to no end.
