We've been through this before. Boring.
It's pretty well proven now that everyone will not turn to the Internet as their major source of information. They will not click on the ad's as much as people want and doing things to encourage clicking discourages visits, and Internet marketing isn't cost effective for big brands (as noted in the article). It's not worth their time/trouble/money to create special ad's for "Bob's Linux World".
The Internet sucks for making money. It's basically a pork generator for government and a silly toy to keep otherwise boring people out of the pub. Huh. Maybe it's not so bad after all.
