Wet or dry?

Right - let's get serious.  Do you wet your toothbrush before you put the toothpaste on?  Somebody has asked the question on Twitter and sparked a big discussion.  You would think it was hardly a matter of great import, but many people seem to have a set routine for cleaning their teeth and stick rigidly to it.  There seems to be a pretty much even split between wet brush and dry brush, but I particularly liked the individualist who tweeted "I wet the toothbrush but I squeeze the toothpaste on my tongue".
