I thought this was an exceptional post and it's something that I have been trying to understand. A big part of me writing this blog is trying to really feel how technology is changing the way we communicate and it's ramifications for friendships and businesses.
Read Fred Wilson's post. Look at the way he builds on someone else's idea, bringing additional thoughts and promoting it to an even broader group of people. Now I'm promoting it to the 35+ daily readers of Kenny Kellogg. Maybe one of you will add something and promote it at the dinner table, a Facebook feed, or through your own blog.
This little virtuous circle proves the exact point of the posts, that technology is reducing the "transaction costs" that a firm is built to handle more efficiently.
