oh. this is interesting. Is there a place on Stack or Linkedin where I can tie my profiles together? I did a quick scan and couldn't see anything (or should I put it in my stack-bio?).
I don't know of any way to link them. I post using my real name on StackOverflow, for precisely the reason of "brand management" or what-have-you. Presumably my name and current employer were unique enough for the recruiter to put two and two together on his own.
