Right now, they couldn’t kill gmail without basically committing suicide.
I much preferred the way it worked to facebook, whose interface and navigation metaphor and lack of guest logins makes me consider it to be a piece of feculent sludge. Unfortunately, the fact that it gained traction overrides all such considerations for a social media site. thus, I put up with it along with everybody else.
Right. Functionally it was much better than Facebook, which got its traction just because it came first.
With Google+, you could control what was seen with much more flexibility–like having different accounts for different purposes, which required some thought process.
Facebook, on the other, catered to simple-mindedness, and it became the standard.
They required you to have a Google Plus account in order to comment on YouTube. If you no longer have a Plus account, how will commenting be controlled?
Note that one of those bullet items is “Commenting with outdated versions of the YouTube mobile app”. It appears they had to tweak it a bit to decouple it from Google+. Also “Channel art and channel icon editing on mobile”.
You might want to check if you have a Google Apps For Education account, GAFE, since G+ is not shutting down over here for GAFE users. The last number I have is that roughly half of US K-12 use GAFE, so that is quite a lot of students and staff that are not affected.
