I think that the question is "How can I mitigate the risk my online identity poses?"
Once on the web I dont think you can get off, the tag I use on HN is one I have used for years, but in those past years I was always a lurker almost never ever commenting (until recently). Now when I search my tag on google HN comments come up, my NSA comments could label me as anti-govt, but thats not the case.
Without going RMS I dont think you can really get off-web if you still want to use the internet in any fashion.
