The prompt used to show up everytime you log in. If you use multiple computers, an authenticator or multiple accounts, that is quite frequently.

Since YT comments are now G+ comments, I believe it now shows up every time you try to interact with anything, such as like/favourite/comment etc.

I turned my YT account into a G+ page when the option became available as a way to get rid of the prompts without using my real name on YT.

I just liked and commented and nothing happened. I even left the 'post on G+' checkbox enabled and it still doesn't show up on my G+ profile. I've setup youtube to use a pseudonym, btw.
