YouTube's new tools bury bad commentsVideo creators have new moderation powers, Androids can be locked remotely, and iMacs get a few upgrades.
YouTube is working on a new way to bury awful comments. I'm Bridget Carey and this is your CNET Update. If you browse videos on YouTube then you've seen your fair share of hateful, obscene and downright despicable comments left by other users. YouTube is owned by Google and the company has struggled to find a way to elevate the quality of conversation, but still let people keep their anonymous handles. So starting this week, YouTube will push certain comments to the top such as comments from videos' creators, popular personalities and people in your Google Plus circles. The top comment won't just be the most recent, it's the most relevant. Video creators can also block certain users from ever commenting or block certain words to make moderating a little easier. Google's Android Device Manager now has a new trick to protect your phone data from getting into the wrong hands. You can now remotely lock the phone with a new password. The Device Manager app first have the ability to remotely ring the phone or tablet in case you lost it somewhere in the couch cushions. You can also wipe all the data from afar. Two-hundred million Apple mobile devices have upgraded to the new operating system iOS 7 and 11 million people began trying iTunes Radio. It's the new streaming music service that's only available now in the US-- 11 million users is 4 times the number of unique listeners that Rhapsody had in July and if it keeps growing like this, it will only take a month to beat Pandora's numbers. Of course, there is something to be said about people who just try something versus actually sticking with it. Remember how the social network Google Plus gained millions of users right away, but people were still spending more time on Facebook. iTunes Radio is available on mobile devices and also in the latest iTunes software update. Apple's iMac all-in-one desktops have been updated with new models that have Intel's fourth generation quad-core processors, advanced Wi-Fi capabilities and faster flash storage options. Apple says these new iMacs get a wireless connection that's up to 3 times faster than previous desktops that is when it's connected to a 802.11ac base station. If you are looking forward to using the BlackBerry Messenger BB Maps on your Android or iOS device, you'll have to keep waiting. It was supposed to come out over the weekend, but an older bad copy with a glitch was leaked for Android users and over a million people downloaded the bad copy. It's causing some troubles so BlackBerry is now trying to block the bad version before releasing the official copy of the app. That's your tech news update but you can get more details on these stories at cnet.com/update and follow along on Twitter.
