It's pretty simple. I was hired by Yishan and reported directly to Yishan to lead the cryptocurrency engineering wing of reddit. This was his idea - and I was happy to lead it. Yishan then suddenly quit, and new leadership took over. The new leadership is not interested in pursuing cryptocurrency at the moment.
Well I'm not really sure, because it felt extremely turbulent while I was there for my brief 4 month tenue. I think the culture will change. I think the culture was a little more loose, autonomous, and with little management before. I think it will be more hierarchical and managed moving forward. However, please realize that I have extremely limited experience at reddit and may simply be wrong about that.
