Have you pinned yet?

First we pinged, then liked, and even tweeted. Now, we pin. Pinterest, a pinboard-styled social photo-sharing website, is the new obsession, with many predicting it to be the next big thing.

Pinterest lets users share their favourite images or videos and create a virtual pinboard, showcasing their likes and dislikes. You can pin images and videos from anywhere and follow pinners who share similar interests.

Pinterest users use themed 'image boards' and populate these boards with images or videos known as 'pins'. Pins on a given topic can be grouped into boards.

Launched in 2010 by Yale University graduates Ben Silbermann and Paul Sciarra, Pinterest has been visited by a whopping 13.76 million users worldwide, according to ComScore, a web measurement site. Pinterest has got Indians hooked too. "With other social networking sites, you end up reading a lot of things you don't really care about. But, osn Pinterest you can follow things and pinboards that you are actually interested in," says Purnima Parashar, 25, an avid user.

In recent months, the online world has been afflicted by several legal concerns. In an attempt to address copyright issues, Pinterest allows users to upload pictures from anywhere, but has introduced a system that allows a website owner to stop images from his site from being shared. But Supreme Court lawyer and cyber law expert Pavan Duggal says, "When you get to go and share on an online platform, any expectation of privacy should be left out. Social media firms are not made liable for any third party data information or communication link made available by them. Unless cyber laws are tightened, not much can be done."
