After the big SSO update yesterday on TD.W, It seems ti be the only site I can log into physically, and GA.W uses my username from there now. My karma transferred from there to here...
I personally, do not like the thought of having my accounts linked together. I expected to remain an anon in both sites, this appears to be a break of anonymity.
I can understand wanting anonymity, but your activity logs on your account are separate for each site. If anyone wants to see my TD.W comments while on GA.W, they can't; and vice versa. So if you just don't want people snooping around your account history, then it already has safeguards in place. Just info for anyone curious.
Not really a safeguard. Nothing stops them from just coming to the other sites and looking for your same username and seeing your history.
