Today’s Telephony 2.0 Reading List:

• Freakonomics Blog: Future SAT Question: MySpace is to Facebook as Yahoo is to ___?

Telco Take: The answer is Google, as Freakonomics “discovers” socio-economic self-selection in the Web 2.0 world. Google (and Facebook) are most popular among users defined as “Affluent Suburbia,” “Upscale America,” and “Small Town Contentment,” while Yahoo! is most popular among “Struggling Societies,” “Urban Essence,” and “Blue Collar Backbone.” Cross-tab that with typical telecom status levels including: “SmartPhone Business User,” “Unlimited Texter on Parent’s Family Plan” and “Buys Calling Card Minutes at Wal-Mart” and you might just have a *telephony 2.0* world-view.

• TechCrunch: Amazon Web Services Goes Down

Telco Take: Pure “five 9s” network guarantees are going to be difficult if not impossible to meet in the “cloud” computing world — data centers *will* go down, in both planned and unplanned outages. Here’s a good take on the “99.99%” myth when it comes to data center SLAs.

• Harper’s: Keyword: Evil and Google Data Center Map

Telco Take: A look inside a soon-to-be-built Google data center, with the computer area measuring 68,680 square feet and attached cooling stations at 18,800 square feet. The Harper’s piece focuses on the power requirements of such a facility, with a brief but poetic look at the “arms race” occurring along Washington state’s Columbia River as company’s look for cheap fuel to power their “cloud computing” centers.
