Just so you don't think I'm ignoring you...
I do e-commerce. Started out in graphic design, moved to user experience and marketing deployment and metrics, then project management and eventually executive management. There aren't a lot of executive e-commerce positions here, and most project manager positions want certification, which I don't have. Then specialist positions (marketing campaign management, etc) want people who have devoted their careers to those specialist positions and not a jack of all trades like myself. I guess I worked myself into a relatively narrow niche.
I have toyed with starting my own thing, but business startup requires money and that isn't exactly in plentiful supply right now.
Anyway, no need to respond... just wanted to answer your question.
