Pinterest [1] and Instagram [2] may be the two largest. And I guess technically Twitter [3]. But Google is so massive that I'm not sure it really would impact their overall market cap at this point. For example, Twitter is about 2% of Google's $640 billion market cap. Although, Instagram is worth around $50 billion now, which might be primarily because of Facebook, but in the most generous case could've added around 8% to Google's overall value, which is moderately significant. Anyway, I applaud their effort, as I think it has a significant chance of empowering some people to build some awesome stuff that they were otherwise too hesitant to go at alone.
