... I should be in bed! I stupidly thought "oh, I wonder if there are any new rumours about Harry Potter 7" about two hours ago.
found this great site called MuggleNet and, in particular, this page which lists essays arguing for and against popular theories for book 7.
really worth a read if you're interested in HP and have a spare hour or so (or are at work and should be doing something far more important, but have got procrastination down to a fine art!).
update: ok - am actually going to bed now (1am...)
