I was just e-mailing a few friends about events that were useful or fun and now my friends of 20 or more have become a mailing list of 7,500 people and a virtual community of at least 10,000 people.
I started a simple list of what I thought were cool events, arts and technology stuff.
This is a mistake. eBay bad and robotic, Craig's List human and good. And now on the way to selling out.
