I remember tinkering with it at that time. It was an exceptionally good tool, a Swiss army knife, but at the company we could not find a real use case for it. Alas it was a small team. Most businesses had their more or less working solutions, and habits hardly change. I think it was shut down too early, not giving enough time to get in. Providing a more business-oriented solution instead of the near-bare "API" and being a tool, it could have been the best collaboration tool of the current situation...
