Personally, I avoided it specifically because of all the "you must use this" shenanigans around YouTube and other services, as well as the Real Names policy brokenness. They could have had much more loyal users if they didn't pull stunts like that.
As someone switched on to those kind of arguments I can definitely understand - but to the every day lay man, I wonder how much a real name policy really would have mattered...
(seeing the other side, I can imagine how people uneducated in these things are also naturally suspicious - my grandma is probably more cautious with her data than any other person I know - perhaps knowing the specifics of threats rather than just fearing privacy leakage as a generic fear inducing concept is worse?!)
Many of the people most affected by the Real Names policy were not "techies".
