Tumblr's not alone -- Innovation Works also has a pretty decent copy of my last start-up, Flurry, called Umeng. (For the curious, compare the product at flurry.com and umeng.com.) I've been watching Umeng for a bit and the services have slightly diverged, presumably because Umeng's learnt a bit more about the Chinese market and adapted its product. But the initial product was just a straight-up clone. I am a little surprised to see this from as respected a person as Kai-Fu Lee, who I'd expect to be innovating, but you just have to shrug. This sort of thing happens in business, and it's not worth getting too excited about.
