BlackBerry is said to warm to idea of a breakup. Bloomberg reports that a break-up would be "more appetizing" to the struggling device company than simply selling it off in one big chunk. "A breakup would let parties bid for BlackBerry’s most valuable pieces, such as its patents or enterprise network, said the people, who asked not to be identified because the talks are private."

Amash: Congressional oversight of the NSA is a farce. While top lawmakers say they've held classified briefings to inform members about the NSA's surveillance programs, Rep. Justin Amash (R-Mich.) claims the details discussed often zeroed in on publicly available information.

That account also started out with the profile text ‘this is a Twitter experiment’, and was later folded into Twitter’s products after it garnered a lot of positive responses on Twitter at large."

The Secrets of Bezos: How Amazon Became the Everything Store. In an excerpt of its senior writer Brad Stone's new book, Bloomberg Businessweek does a deep dive into Amazon's corporate culture: "It’s one of the contradictions of life inside Amazon: The company relies on metrics to make almost every important decision, such as what features to introduce or kill, or whether a new process will root out an inefficiency in its fulfillment centers. Yet random customer anecdotes, the opposite of cold, hard data, can also alter Amazon’s course."
