There are many things they did that are very applicable to current startups. In particular governance models and transparency are very much issues that current startups need to worry about.
The point about Know Your Customer is also an important one. In the 90's when e-gold started there was a lot of experimenting with this. Most people in the industry were weary about government involvement, but didn't think it was going to affect them.
At some point it isn't inconceivable that social networks, email service providers and others will be required to follow similar Know Your Customer procedures to banks. Several countries are already starting to institute this.
These regulations are what make online payments that are as easy as cash legally impossible. It's a serious detriment to startups.
Sorry for continuing this particular topic of conversation, but that is entirely false. Most economists don't advocate a gold standard, but you will find serious discussion of it in any mainstream economic journal that touches on monetary policy or history. The monetary system that served most of the Western world for several millennia is not considered "nutty" in academic circles.
At least, we discussed works by several modern advocates of the gold standard that regularly publish in mainstream economic journals in my Money and Banking class.
