Been a Google + user since it's inception. I deleted my Facebook account and rarely use Twitter anymore. The G+ comments may actually bring some civility to that rancid cesspool that is the youtube comments section.
anything is better than facebook but i just dislike G+' layout and just hate it as a whole personally, but yeah true it could bring down trolls i guess, but youtube was the place you could express your views on videos and google forcing you to use their website just to do that is just kinda shitty
Google+ will always be my favorite for many reasons. True, Google may have screwed up (badly) with the integration of G+ into YouTube, but overall it is a much nicer place than say, Facebook or Twitter.
