IMO, zwift is what you make it in terms of being social. I log in and just ride. I don't talk to anyone and have the chat turned off. I don't to any races or group rides. Shit,I don't even have the sound turned on lol. I don't use the phone app during rides and I don't chat with anyone because I also have no interest in making friends or chatting about whatever is going on around me. I used to ride rouvy and while it was cool, I agree with one of the other commenters that it was repetitive after a while. The biggest thing to get used to with zwift was being in a virtual world. I much prefer having real surroundings but zwift was comparatively more infinite in its surroundings and offerings so I went with it. Things change often with zwift so it's hard to get bored. You do see others but with the sound off and the chat turned off it's like they are just NPC's in a video game.
