The “X for Y” clones are at it again, this time in the form of “Pinterest for Videos” ClipClock which is backed by $2.5 million from Russian VC Runa Capital. The company has a Web product and an iOS app, with Android and Windows Phone 8 said to be coming soon. The model was less than successful in the “Instagram for Video” races, but whether this category will be different remains to be seen. [Source TechCrunch]
