Google have today announced and launched their latest social venture "+1". The new and fully integrated feature allows users to give websites a "public stamp of approval", viewable to friends who come across the result in search. Think of it as a kind of Facebook 'Like' for search results.

This is undoubtedly the big G's hardest push into social so far, and although 'the like button' is now well seeded within the internet community, Google's traffic monopoly sets them in good stead for the title of content sharing champion.

So, where do you sign up? Despite the hype, the function is only in 'experimental mode' and therefore resides under Google labs, the company's opt-in-only site where new and upcoming features are tested on consumer guinea pigs. Want to get in on the herd? Then read on...

On Monday, Apple rolled out their latest software update for the iPhone, iPad and iPod Touch. iOS 4.2 brings a handful of new and useful features to the big A's mobile line-up, including over-the-air printing. AirPrint makes it easy to print e-mails, photos, web pages and documents straight from iOS to your WiFi-enabled printer. Although the functionality has been a long time coming, many feel the final software is crippled by it's limited compatibility with existing wireless printers. In fact, to date there are only 11 products on the market which work with AirPrint, all of which are from HP

So if you, like us, are perfectly happy with your current print-out setup, you might want to check out Printopia for the Mac, a superbly simple $10 application that restores some function to Apple's crippled AirPrint update. Read on for our video demo, verdict and download links...

It was this fateful day in 1985 that Nintendo released Super Mario Bros to the world. Well twenty-five years down the line and over 200 game appearances later, everyone's favorite Italian-American plumber is still saving peach, beating bowser and generally just kicking ass. Thus, Mario has been forever immortalised as the founding mascot for the console video game.

Unsurprisingly the mushroom kingdom crusader has built an epic fan-base, stretching over numerous gaming consoles and genres. From the best-selling platform games to racing, role-play, fighting and sports, there's a Mario for everyone!

What better way to pay hommage on this silver celebration than by handing over to the YouTube generation. So without further ado, here's our top 5 YouTube tributes to the one and only super Mario.
