content: I have tried all of them with the following results:  Tor - damn slow and not suitable for all services, but of limited use sometimes. Freenet - never actually took off the ground. I2P - damn slow, some sites come up, others don't. Not much to see there - sites are few and quite boring. Possibly you have to know the right places and stay online permanently to get some bang out of it.  Of all these Tor seemed to be of the most practical use, and I2P seemed the most promising, though the concept of Freenet appealed to me the most. So, no much to be excited about right now, but possibly some day in the future it will work. With the authoritarian governments, belligerent SJWs and lying media there is just no other way.
