Didn't Google make everyone a Google plus user in the end wether they wanted to or not? To be honest it didn't use it I did use Google wave for 3D printing (reprap) discussions though, remember that that was even more obscure? 😁
Yes I think so. Then when G+ went away, people on YouTube comments would harass me asking how the eff did I have a verification mark (I got it from G+). Lol. Youtubers who didn't G ploss were pissed when they had to make a profile lmao
