Hamsphere and similar

Hamsphere and CQ100 have been around for many years. They behave as ham radio (simulated rigs, bands,antennas, contests ,etc, but use the internet as the communications medium rather than the ionosphere. 

I guess both have their places for some although I have never really been interested. It is just too easy for me and lacks the element of research and experimentation. Each to their own.
