My #1 Doh moment so far

I sold the domain name socialgraph.com for $1500 to some woman claiming inexorably to want it for "just a personal homepage". Ah well, I thought, I will probably never get around to building something for this particular domain anyway, might as well make a few bucks. A few weeks later, Mark Zuckerberg is on Web 2.0 Summit telling about something he calls the Social Graph and I whip up the whois results for socialgraph.com. Administrative contact: someone@facebook.com Doh! Would probably have been able to score a few more bucks from recognizing the term social graph before Mark did. Proof is in whois record history for socialgraph.com.
