I have said this before, but when I first used AB, I thought that the general idea was you only asked as the last resort after trying your ref books, dictionary, spellchecker and Google etc then ask if you still cant get it, I still do this but if I have been away for the weekend and want to catch up then I go back on AB and most of the answers are already there for me, but its not the same as finding it all out for yourself.
some people are just lazy bu**ers, they want the prize money but dont want to make the effort.
