I had a G+ account attached to my google apps for domains account. Only used it to keep up with the statuses of the Dart team (as only about 3 people I know are on G+)
i started getting messages on youtube about do I want to use my real name? no I don't. a week later, same thing. ignored. then it seemed to get to the point that I couldn't do anything, even view videos without this same old shit happening. either use your real name or create a g+ channel for your login. feck off I don't want either. so I deleted my g+ account, telling them why.
just checked. although my youtube account works, when i clicked to add a comment it went back to "if you do this you will have to create a g+ channel with your name". i clicked no, message at top of screen goes "OK, we'll ask you again later".
totally fusking bizarrely I just uploaded a video and made it public and it didnt ask me about creating a google+ channel.
contrary to popular belief I do add useful comments at times :) though this whole g+ channel thing means i'm not posting comments on youtube anymore. screw it, really not worth it. but people will just click ok because they are idiots.
bit like the thing going round FB at the moment, the 'whats your brain age' test where you have to agree for them to be able to see all your contacts and all your posts etc. and people still click ok.
