I have a professor who worked there for 6 months. He said it was one of the most unorganized positions he's worked at. There's no focus, and during the media blitz from TED, he got way too much money, and didn't know how to spend it effectively.
I've been following OSE casually for several years - it was an intriguing proposition. The online presence gives the impression that it has collapsed. I think Marcin has squandered the energy and we'll not be seeing anything more from it.
