I have maintained a portfolio for decades, as have most of my colleagues. I don't put it online, though, because I don't see an advantage in me doing so (but I can totally see others could get an advantage doing so). I provide that portfolio to others personally when I'm selling myself in some way (job interview, wooing investors, etc.). But I'm old and most of my colleagues are within a decade or so of me. I wonder if there's been a generational change. Maybe this used to be a common thing and just isn't so much anymore?
