Square finally closes $200 million round at a $3.25 billion valuation [ALLTHINGSD]

In an interview several weeks ago, Square COO Keith Rabois said that the company plans to start marketing itself aggressively. It already has commercials on TV, and a wide-ranging deal with Starbucks announced last month will also help.

H-P tries on a sleeker look [THE WALL STREET JOURNAL]

Redesigning its devices is more than just a cosmetic project.

In H-P’s most recent quarter, PC revenue fell 10% from a year earlier to $8.6 billion while the unit’s operating income tumbled 27%. Overall, the company reported its biggest-ever quarterly loss.

The full announcement awaits in the PR after the break.

As predicted, Google+ passes 400 million registered users, now has 100 million monthly active users [THE NEXT WEB]

Yet the real story here isn’t the 400 million number, but the 100 million one. Google+’s main competitor Facebook doesn’t even bother talking about registered users because it know the number is meaningless. The social networking giant only talks about monthly active users, of which it has 955 million as of June 30. Both Facebook and Google are talking about combined desktop and mobile users.
