I don't have much to add to this "I've been around so long I've seen" thread-- it's a pretty good read on its own. But even though I haven't been around that long, relatively speaking, I will say that I've been around so long that...
... I remember when Warsong was just a hunting camp, and not a graveyard for millions of PVPers.
... I had to ask a guildie in Ironforge to help me find a group for ZF when I was in Tanaris.
... I know there was a time when you could queue for a battleground at 19, and level to 21 before you joined the instance.
... I remember when dying actually cost you experience points (no, wait, that was back in Dark Age of Camelot)
... I remember when Chuck Norris was just a guy on a TV show, and not a supreme Godlike being.
Ok, maybe that last one was never true. Nickelplate (a player who posts on page 4) gets it right when he says he remembers "when people lived life at a slower pace and the idea of feeling nostalgia for things that happened only 2 years ago was laughable," but a little nostalgia for nostalgia's sake never hurt anybody, Nickel. This game has changed a lot over the past few years, and considering it's all going to change again pretty soon here (when the next patch, and, soon, the expansion gets released), now's a good a time as any to take a look backwards.
