Michael ArringtonMichael Arrington Responds to Allegations (SocialTimes)
In a deliberately vague statement, TechCrunch founder Michael Arrington has effectively denied allegations that he physically abused his ex-girlfriend. The former lawyer did not mention the accusers or the accusations by name in the response he posted on his personal blog, but the news headlines in the past week have centered on a Facebook status update written by RTist.com founder and CEO Jenn Allen, a former girlfriend of Arrington’s who said that he had cheated on her, physically abused her and threatened to murder her. FishbowlNY Arrington wrote on his site that “All of the allegations are completely untrue” and that he had hired a legal team to ”represent me in the legal actions against the offending parties.” He continued: “I know this isn’t, for now, much information. I will have a full and complete response to these allegations sometime later this week. My goal will be to direct as much sunlight as possible on the issues so that the absolute truth can be known and I can begin to put my life back together.” Gawker Nik Cubrilovic, an entrepreneur and programmer, lived with Arrington at the time he was dating Allen. In an email to Gawker, Cubrilovic said that after speaking to Arrington he is “100 percent convinced now [Allen] is lying.” He painted the picture of an obsessive ex-girlfriend whose only aim is “to destroy Arrington.” Business Insider Now, former TechCrunch CEO Heather Harde has commented on the allegations. She wrote in part: “I simply do not believe any of the allegations to be true. TechCrunch Crunchfund partner Pat Gallagher and Techmeme’s Gabe Rivera also gave brief statements around the time of the post’s publication, attesting to Arrington’s character: “I’ve known Mike since 1989,” wrote Gallagher on Facebook, “We went to college together, have worked together, have lived together and I have met just about every woman he has ever dated. I have never seen him physically threaten or harm anyone, woman or man, and can’t imagine him doing so.”

Facebook Blocks Access to Unauthorized Pre-Release Version of Home (AllFacebook)
Some tech-savvy users of Android devices were able to experiment with a pre-release version of Facebook Home prior to its scheduled release in the Google Play store Friday on selected smartphones, but it seems that Facebook was able to pull the plug on the unauthorized preview. MoDaCo unearthed the pre-release version of Home from a pre-release HTC First, and it said that while it was able to get that version working on Android devices with maximum resolutions of 1,280 pixels by 768 pixels and the ability to completely uninstall existing Facebook applications, it was buggy and incomplete, with the new Chat Heads feature not functioning, for example. Mashable Mashable attempted to download it as well on a Nexus 4, but only got a blank screen. We had to uninstall the apps — Facebook, Facebook Home and Facebook Messenger — to get the device working again. Los Angeles Times Facebook could not be reached for comment.
