One thing that hasn't been discussed much as far as I can see is that pseudonymous commenting is harder than it used to be. New comment systems like Disqus which track users - for their convenience, of course - make it impossible to maintain multiple identities without basically wiping cookies between every comment. Similarly, facebook integration apps can reveal your identity if you stay logged in to facebook, even if you intend to comment under the pseudonym. I can't comment on a lot of blogs anymore without revealing my multiple identities.
This pseudonym has never been terribly secure - I wasn't all that good at anonymity when I started - but this has always been an UNprofessional space for me and I want to keep it that way.
