Thank you for the welcome! I haven't really played any MMOs except for WoW (Enhancement Shaman), did some SWTOR and Wildstar but my guild quickly gave up on those and I was alone.

Diablo 3 is pretty mellow compared to real MMOs and is an easy one to play for 30 minutes here and there without having to worry about a big group and progression. You just keep looking for gear and see how high of a Greater Rift you can do to try to beat your best score. I think that is why most people like it, it doesn't feel like a job like WoW did.
Hope to see you around and thanks again for the message!
