Here is a good piece of anecdotal evidence from DNJournal’s TRAFFIC Silicon Valley article.

Bhavanie noted the incredible value of leads that can be generated from a good generic domain. His brother is involved in manufacturing in Asia so Bhavanie gave him a related lead that came through his CellphoneAccessories.com site. His brother told him that one lead resulted in more than $2 million worth of business in the last 8 months. On a PPC page, the click might have generated 10 cents!

In a few days I’m going to make a big post of the real evidence why developed domains are better than parked ones.
