It would be nice to be able to comment on YouTube videos (even reply/respond to comments on my OWN videos), but I refuse to switch to G+ and give them that info.
Exactly. I didn't use Google+. I didn't WANT to use Google+. When Google tried to force everyone to use one identity (which didn't work, by the way), my response was simply to stop commenting on YouTube, and stop using Google+ altogether.
There is one person -- and only one -- who now occasionally chats with me via Google Hangouts, and I'm trying to quash that use as well.
All in all, it was a dick move on Google's part, and it drove users away in, well, droves. Have you notices how FEW comments there are on YouTube now, compared to before that switch?
I have been slowly but surely divorcing myself from Google's services. Now, they want to be the judge of how "factual" web pages are, based on dubious methodology. No thanks.
So it looks like Google Search will be the next to go.
