StumbleUpon, one of the original favorites of time wasters on the internet everywhere, has just launched a major redesign that bears more than a passing resemblance to Pinterest. The new StumbleUpon offers a boxy grid of web content that is curated based on a user's interests or what is currently trending on the site. Users can then view, comment, or share the website or video that is presented. New StumbleUpon also includes lists of content and what the company calls "StumbleDNA," which provides each user with an identity based on the content they like on the site.

This redesign was initially released as a beta product in September, and StumbleUpon notes that over 100,000 users opted in to try the beta and have created over 45,000 lists. Now it is making it available site wide for all 25 million of its users. Astute visitors of the site will note that the new StumbleUpon pairs nicely with the refreshed iPhone and iPad apps the company released back in September as well. An Android app that matches the new look of the site is also said to be in the works.

This isn't the first time StumbleUpon launched a major redesign: back in December of 2011, the company released a major overhaul that had a disastrous effect on the site's traffic. Whether or not this most recent redesign will turn the tide for the company remains to be seen. Check out the video below for a look at all of the new features in the redesigned StumbleUpon.
