There seem to be plenty of posts that say "Help!" or "Newbie Needs Advice" and then when I read it , the poster wants to know how many grams of fat in a hard-boiled egg. It's not that I don't like to be helpful, but jeez!
Or sometimes the thread takes a turn that's not apparent from the headline or even the original question.
Or others have answered so well, why reply just to bump the thread?
