The lesson is: treat Bitcoin like a speculative gambling token, ignoring any of the properties which could actually be used to buy goods and services, in the desperate hope that you'll someday be rich.
Or at least that's what most people seem to think when they see articles about Bitcoin Pizza.
At least Laszlo himself has the right attitude about this.
3-4 years ago there were less than 100 people frequenting this forum, and I was pretty happy to trade 10,000 coins for pizza. I mean people can say I'm stupid, but it was a great deal at the time. I don't think anyone could have known it would take off like this.
