As much as monopolies hurt business and innovation I set two benefits to this:

1) As a publisher using Adsense I have much more relevant ads with more advertisers flocking to one supplier.

2) As an advertiser I have access to a nearly unlimited amount of channels in almost every market.

I'm sure one day we might look back at this as a negative thing but for now I still hold respect for Google.

yahoo made a smart move - problem creators now have to calm down for a while - it will give some time to breath and move their strategy as a success ... kind of wait and watch.

as pg once said that if enough time and freedom is give to jerry yang to run the company the way he wants then he can prove his worth - i think the time has come that he proves himself and get back the reputation and business as earlier ... good luck to him.
