These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.The goal is to fix all broken links on the web . Crawls of supported "No More 404" sites. ||||| The Google+ social network launched with much fanfare at the end of June. As the 100-day mark approaches, Google is looking to further expand the audience. The search giant is now dropping the invitation barrier and making the service accessible to all users. 
 
 In a statement on the official company blog, Google engineering senior vice president Vic Gundotra explained that the site is ready to move from "field trial" to full beta. Google+ has adequately scaled with the growth of the audience so far—it's not clear how many users connect to the site every day, but Gundotra says that over a billion posts have been shared since the launch. 
 
 In addition to allowing anyone to sign up for the service, Gundotra also announced other new features that are going to roll out on Google+ over the next few days. The Hangout feature, which enables multiuser video chat, is going to be supported on mobile devices via the native iOS and Android applications. Google is also expanding Hangouts in the browser, offering integration with Google Docs and screensharing. 
 
 Alongside these changes, Google is also starting to open up APIs to third-party developers. They have started by enabling programmatic read-only access to public user posts. Not enough functionality is exposed through the APIs yet to support a full-blown third-party desktop client, but it's not a bad start. Google is also working on APIs for Hangouts, which will make it possible for third-party developers to integrate their own services with the video chat system. 
 
 In our own experiences with Google+, we found that the granular sharing model helps differentiate the service and will likely give it staying power. It's already off to a better start than Buzz, which was plagued with privacy problems and didn't offer much innovation out of the box.
– If you’re one of those poor, sad souls who couldn’t get a friend to hook you up with a Google+ invitation, good news: It's your lucky day. As of yesterday anyone can sign up for Google’s social networking service, Ars Technica reports. Google still considers the service a work in progress, “but with the improvements we’ve made so far we’re ready to move from field trial to beta,” a senior VP wrote on the company blog. Google has also added a variety of new features, including the ability to search for specific posts and people, and a host of new features for its “Hangouts” video chat function. You’ll now be able to access Hangouts from Android phones, for example, and you’ll be able to name them, integrate them with Google Docs, and more.
