Congratulations. One of my main critiques of Urbit was that I've been waiting years for something more widely usable and it seems that finally things are turning around.
There's a lot of very shallow and superficial negative opinions about Urbit, while it's one of the most interesting projects being developed online, IMO.
I do have my own set of criticism (see: https://dpc.pw/pragrammatic-critique-of-urbit), but overlay I hope it will be successful.
