WIKIs

Ok, so I've set up my very first Wiki and all I can say is 'Wow'. I have no idea what to place in it. At the moment all it contains is 1 video from YouTube about abbrivations in 'online speach' with characters from the World of Warcraft game and a link back to my blog. I would be happy if anyone could give me some more ideas as to what I can post on there.
