First Slashdot account: CmdrTaco, 1997
Slashdot's discussion areas and user accounts were the granddaddy of the modern social Web. Slashdot user IDs were assigned chronologically, with the upshot being that people with lower numbers were users who had been around longer (and thus had more geek cred). It's no surprise that user number one was the site's founder, the now retired Rob "CmdrTaco" Malda. Perhaps of more interest is this chart showing the drop-off rate for the first 1,000 Slashdot users; as of August 2011, only about 300 remained active.
