Do it! The catharsis is palpable. My metric is: am I happy with the work? i.e. I don't really consider myself "primarily" any of the things you see there. I'm a bit of all of them. So, as long as I'm satisfied with the quality of the work (regardless of discipline) then I publish it. Admittedly, it mixes one's professional, personal and creative personas - but I think that's a reasonable trade off.
