none of those examples involved people getting a programmer cofounder.
Arrington is the sole founder, and his "startup" was just a wordpress install.
Anne Wojcicki doesn't have a programmer co founder.
Guy Kawasaki paid thousands to build alltop, so doesn't apply.
Seth Godin is a marketer/blogger, so once again, no technical cofounder.
Arrington co-founded Achex a epayment system prior to techcrunch with a technical co-founder.
Kawasaki co-founded (and sold) Fog City Software with programmer cofounders.
Godin has founded a number of startups including with programmers I believe.
You see business guy founder's companies regularly on techcrunch, how often do you bother to look into the background of founders on news stories ?
