can you post this every couple weeks? thanks brad.

Chris - A margin is almost impossible to defend in *any* industry unless their are defendable barriers to competition. To carte blanche say that the Internet is any different than another industry doesn't feel right, especially when margins in most internet businesses are SO much healthier than in other sectors.

In consumer electronics, for instance, it is typical to see 10-15% margins on a product and even for that to be eroded quickly as knockoffs hit the market. Compare that to Ebay and Google.

Don - I had fun on the panel, good seeing you again.
