I wondered over to programmers.se today from SO for the first time, and posted a response to a users question. I was a little surprised at being allowed to do this by just providing my name and email address, but once I saw my SE profile pic come up, I figured it must just be a common sign-on (I'm using OpenID creds, via the verisign PIP site)
This was the question - and my response below Do software engineers really need to know low level stuff anymore?
So, tonight I'm logging in from my home system. As before, I first log into SO with my OpenID, and then navigate to here via the StackExchange navigator, and I find I'm not logged in. I hit "Login" entered my OpenID, and it found and linked my accounts.
The problem is that my new account here doesn't have the question listed as posted by me - so it appears that is some other or "anonymous" account that just happens to have the same name and profile picture.
So - I'm mentioning this as it was a bit odd of an on-boarding experience that might be useful to consider for new user workflows.
I'd also be keen on getting that answer added to my real account, if there's an admin-type that I can appeal too!
Thanks - I'm very impressed with stackexchange site functionality and am glad to see it branching out.
