LifeProof has made a name for itself as a maker of super rugged iPhone cases that you can take in the ocean, to the beach, or even to the top of Mt. Everest. This thing can survive in some surprising environments

Crowdsourced labor startup CrowdFlower is launching version 2.0 of its Real Time Foto Moderator today, with updates that should make RTFM more useful for apps with adult and edgy content. CrowdFlower first announced RTFM last month, pitching it as a self-serve tool that app developers can use to tap into the crowd and make sure the images shared by their users are appropriate. This was the company’s first big launch after co-founder Lukas Biewald (a former roommate of mine from college) rejoined as CEO , saying he wanted to create self-serve products that could be used beyond CrowdFlower’s enterprise customer base.

“This is epically important,” tweeted Wikipedia co-founder Jimmy Wales, about a new simplified editing platform aimed at massively expanding the number of people who contribute to the online encyclopedia. A deceivingly tiny percentage  of users actually contribute to Wikipedia, despite the foundation’s ernest attempts at making it an inclusive, democratic creation of mankind (estimates put the active contributer base at around 0.7%, who make up 50% of the entries).

Location-based apps and services like Foursquare have made significant inroads among consumers in the last few years, but most of the recent developments around location-based apps have bypassed the business market.

Facebook will have to give users more control over which of their actions can be promoted in Sponsored Stories, as part of a settlement for a suit claiming the social network violated California law by using people’s names and images along with advertisements without compensating them. The change could have a negative impact on Facebook’s advertising business, which increasingly relies on Sponsored Stories over traditional ads that do not include social context of what a user’s friends Like

Well isn’t this interesting — with just about five days to go until Google’s I/O conference, the company may have just accidentally spilled the beans about their next big Android release. For a brief time, users who tried to purchase an unlocked Galaxy Nexus from the Google Play store was greeted by a blurb describing the device as the “the first phone with Android 4.1 Jelly Bean.” Assuming this isn’t just some random mistake, Google has confirmed what nearly all of us expected their new update to be called, though there’s sadly little other information to go on at this point. Going off of past experience though, don’t expect Verizon’s LTE-enabled version of the Galaxy Nexus to get the update quite as quickly as its unlocked cousin.
