Earlier quoted context omitted.
How has market cap got anything to do with monetizing the site? You're suggesting that if Google was smaller then that would make this site more appealing to advertisers? That having more advertising companies would make this site more valuable?
if Google didn't make site more appealing, Google2 or Google3 or Google4 or SomeOtherCompetitor5 might but the problem is that there are no "2,3,4,5' options - there's only one. And it has no incentive for "good people" to leverage
But let's imagine you're CEO of option 2. What do you think you might do differently which would make this site, in its original form, appealing to advertise on?
Having multiple ad companies doesn't sound like an improvement when the advertising space on offer doesn't seem to be good for advertising.
Or to put it another way, do you feel this space does have value, but Google is leaving that value on the table? If so, why hasn't some other company taken advantage of this value?
