For everyone trying to figure out when they signed up: a poster named MyLongNickName linked to some research he did showing which UIDs correlate to which years.

To take it back a bit further than he goes, I'm 31494 and registered sometime in late 97, early 98.

What's interesting about the numbers he presents is that there's a definite increase in growth rate (~2x) around 2008-2009.
