They liked your comments. Nothing you can do. 2 billion people use or look at Youtube.
Actually you didn’t have to sign up to use youtube. They will nag you multiple times and try to force you to get an account, but you can ignore the requests. Unfortunately it is too late for you since you signed up.
I use Google for email, have a Picasa (photo sharing) account, but I will NOT sign up for Google+.
I did, and it completely screwed up my Picasa account. Google gave instructions for opting out, and I did.
You want the convenience of Gmail and Picasa?
The price is track-ability.
And that’s the way it is.
