Satoshi Nakamoto last seen in 12.12.2010... 10 years ago? It is hard to believe this project called Bitcoin is still ongoing. The reason why Bitcoin is still around it is because it is decentralized and open source.

Regarding your question, we don't use too much bitcointalk. Too much stuff going on here. We use telegram and GitHub. The network is up and running for more than 3 years. WebDollar it is decentralized and open source as well. In the last past months we have been focusing on building a decentralized and anonymous peer to peer exchange. Still some work has to be done.
