As far as I know, the platform exists for quite some time. but its activities are moving quite slowly. we would like to see a more active development of the idea.
this is really a good idea. it is not necessary to delay its popularization and development. it is important, that it begins to function in the near future.
What do you mean exist for some time now? They only have a webpage right now and aside from that everything are still a mystery on what are they really trying to launch.
I have been waiting since they open the ANN thread to launch their platform and open it publicly.
