I have noticed this on certain forums too; a question that had over 100 views but either 0 replies or only 1. Many times that one answer tends to be vague.

Because the title is very vague or doesn't get people's attention. Saying "PLEASE HELP! VERY URGENT!" actually DOESN'T help.
The details might be way too long and not broken up into paragraphs. Or the details might not be descriptive enough. Or they could be extremely confusing.1
