My fark account is old enough to drive in the US. I don't think I really use much of anything that old anymore.
I had facebook from the time when it still required a .edu email, though I quit that. I lost access to my hotmail account years ago after dropping it in favor of gmail. I had IRC accounts going back into the '90s, but I almost never use IRC anymore (and certainly not on those same networks (assuming they even still exist)).
