Misguessing gender from ambiguous usernames is all too common, made more so by different naming conventions in different cultures and languages.  I would have bet nanne was a woman's nick.  Now I'll have to recalibrate.  ;}  And I thought for a long time that kcurie was a woman.  Funny how deeply embedded our gender identification is with our conception of ourselves and others.

We all bleed the same color.
