I'm a professional programmer, and very active on StackOverflow.com.
I'm also a private pilot, and starting to get active on Aviation.StackExchange.com.
For both professional and vanity reasons, I want my StackOverflow profile to tout my programming knowledge and experience. Employers don't really need to know about my flying skills.
Similarly, I'd like my Aviation profile to describe my flying experience. But I don't think my skills with various CPU architectures are relevant to flying.
But ultimately, I'm one person, so I want one login.
It seems that one login == one profile. Is that right?
Does StackExchange have any provision (or future plans?) to have different presentation s of the same person?
