Mahalo CEO and serial entrepreneur Jason Calacanis says Facebook's Mark Zuckerberg has simply overplayed his hand. "Facebook is officially 'out,' as in uncool, amongst partners, parents and pundits all coming to the realization that Zuckerberg and his company are -- simply put -- not trustworthy," Calacanis insists. Case in point, casual gaming company Zynga is reportedly developing plans to get over what Calacanis calls its "Facebook dependency." Calling Zuckerberg "an amoral, Asperger's-like entrepreneur," Calacanis says the Facebook founder has screwed over his users again and again in terms of privacy, not to mention his former employers at …

We're looking at all the things Google has …

Challenging Google and Nokia -- along with dedicated turn-by-turn GPS navigators like Garmin and TomTom -- Bing just added voice-guided turn-by-turn navigation to its mobile app for Windows Phones 6.1 and above.

"Even today ... there is almost no mobile advertising," he said at an industry conference attended by The Wall Street Journal. "The screen is just too small" -- even on many of today's smart phones. Still, Ryan conceded that the iPad is the first mobile device he's seen that could deliver compelling advertising to consumers. At Gilt, purchases made from consumers' …

As if Google wasn't having a hard enough time getting government approval for its AdMob acquisition, WPP head Martin Sorrell is calling for even more scrutiny of the proposed deal. "[Regulatory investigation] should be rigorous," Sorrell told Reuters "on the sidelines" of the World Economic Forum on Europe. "I don't think in the case of DoubleClick it was deep enough and strong enough," Sorrell said of the U.S. Government's supervision of Google's acquisition of the display ad giant for $3.1 billion in 2008.Last November, Google announced plans to buy AdMob -- which controls about one third of …
