Seinfeld taught me that if someone posts about a dead relative on Facebook,
it's OK to ask if their apartment is on Craigslist.

Wired magazine has been covering Internet etiquette since people still used the word "netizen" without irony. How long ago was that? Around the time that Seinfeld was on the air, and I'm not talking about the later years. Everyone knows that when people think of the Internet from that time period, they think of the small Macintosh computer Jerry had in his apartment that virtually never got turned on.
