No matter how invasive the technologies at their disposal, marketers and pollsters never come to terms with the living process through which people choose products or candidates; they are looking at what people just bought or thought, and making calculations based on that after-the-fact data.

The hours Facebook users put into their profiles and lists and updates is the labor that Facebook then sells to the market researchers and advertisers it serves.

The reason why Apple computers have worked so well over time is that, unlike Microsoft, they don't bend over backward to be compatible with every piece of hardware or software in the digital universe. To code or create for Apple, you follow Apple's rules. If you're even allowed to.

For Google, the problem with being a free, abundant, and rather infinite set of services is that it's hard to create much of a stir about anything. There are so many major software service options under the 'more' menu on the Gmail page that they've had to go and add a final item called 'even more.'

Removed from 'Gmail' doesn't necessarily mean removed from all Google servers. In fact, your old emails are the data set from which Google models our behaviors - the real product it is offering its advertisers.

Google did a great job hacking the Web to create search - and then monetizing search with advertising. And Apple did a great job humanizing hardware and software so that formerly daunting computers and applications could become consumer-friendly devices - even a lifestyle brand.

Facebook's successor will no doubt provide an easy "migration utility" through which you can bring all your so-called friends with you, if you even want to.
