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".
Instead one of the last updates brought collections. It is very reminiscent of Pinterest but does not just focus on pictures. It is a very handy way to maintain different streams like e.g. :
-random social banter
- technical subject 1
- hobby 1
...
The mobile interface could better serve this paradigm, but otherwise this is the best social product for me.
