Faring better than some other Internet stocks, Yelp reported strong second-quarter earnings on Wednesday. “Overall, the reviews site showed continued top-line revenue growth and a smaller net loss than it has posted in the past -- a performance that bested the estimates of Wall Street analysts,” TechCrunch reports. In its second-ever financial report as a publicly traded company, Yelp reported revenue of nearly $33 million -- up 19% from the previous quarter, and up 67% year-over-year. That said, Web watchers are still waiting for Yelp to turn a profit. 

Officially, Facebook says it has about 955 million monthly active users. However, as the company revealed this week in its 10-Q filing, it estimates that 8.7% -- or 83 million -- of those accounts are fake. “That's a huge jump, both in raw numbers and as a percentage, from Facebook's last estimate,” CNet reports. “Back in March, Facebook said 5% to 6% of accounts are false or duplicate. At the time, this meant between 42.25 million and 50.70 million users.” Why the jump? Facebook, to its credit, now appears to be doing a better job of identifying and classifying fakes.

Digg's new "Rethought” redesign just went live, and, as expected, it emphasizes simplicity, along with top stories, popular stories and "upcoming" stories. Betaworks -- which recently acquired the social news pioneer for a half million dollars -- says it's changed the Digg score to take social sharing from Facebook and Twitter into account when ranking stories. Also of note, “the front page of Digg will also be editorially driven instead of entirely based on a Digg score algorithm,” The Verge reports. 

Hampering its home entertainment ambitions, Google is pushing back the official launch of the Nexus Q. Unveiled this summer, the spherical black media device plays music and video from Android devices. “The Q is Google’s maiden attempt at making its own hardware (and, unusually, is manufactured in the United States),” notes The New York Times’ Bits blog. “But curiously, it is the software, which is Google’s typical area of expertise, that needs the work.” 

Following Hulu’s lead, Amazon has added its Instant Video Store to Apple’s iPad-compatible App Store. “It looks like a full app capable of not only streaming Prime content for free (with the $79 a year Amazon Prime membership, but the first month is free,) as well as being able to download content for offline viewing,” reports 9to5Mac. Amazon’s Season Pass service is available for TV shows, while episodes are available the morning after show airs on TV.
