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.

One argument against open systems is that they become open to everything, good and bad. Like a Richard Meier skyscraper, the anal retentive, Bauhaus elegance of the Mac does prevent the loose ends and confusion of a less sterile environment. But it also prevents fertility. Apple's development must come from within.

We know that people are less open in conversations if the other conversant puts a cell phone on the table. Even if it's turned off. The sign is enough to close the mind and make a prospective client or lover less likely to do what you ask. As people realize this, they'll start putting away phones or turning them off.

Microsoft's new OS, Windows 7, may finally be a worthy successor to XP, eliminating the clutter of Vista and letting users get to what they want to use without the fuss. All this, while remaining compatible with their IT departments' demands for scalability and custom implementations.

Digiphrenia - how technology lets us be in more than one place - and self - at the same time. Drone pilots suffer more burnout than real-world pilots, as they attempt to live in two worlds - home and battlefield - simultaneously. We all become overwhelmed until we learn to distinguish between data flows (like Twitter) that can only be dipped into, and data storage (like books and emails) that can be fully consumed.

Technology has moved away from sharing and toward ownership. This suits software and hardware companies just fine: They create new, bloated programs that require more disk space and processing power. We buy bigger, faster computers, which then require more complex operating systems, and so on.

Nothing is sacred. And, more importantly...the 'nothing' you end up with is truly sacred.
