Chill.com is the latest Silicon Valley startup to pivot from its original plans. It was a Turntable.fm-esque social service for people to DJ web videos, but now it’s – and we realise we sound like we’re just spouting buzzwords here – a social video aggregation and discovery site. What that means is it collects videos being shared by Chill.com members, while also pulling in videos from each user’s Facebook and Twitter friends. “There isn’t a great networking approach to video,” founder Brian Norgard tells GigaOm. There are several apps doing this kind of thing on tablets, though, while as the article points out, the biggest threat may be Google continuing to ramp up the social features on YouTube.
