One thing to consider is to not engage with the critics. It's hard, I know -- really I know. An engineering mind set might make you not want to "flip the bozo bit", and to learn as much from your detractors as possible.
There may be strategic reasons to get your story out -- e.g. if your co-workers or potential clients are getting a distorted story, but the personal cost in time, annoyance, and loss of peace of mind is high.
So maybe, if possible, take a usefully arrogant / narcissistic view as a form of sanity-protection. Why do you need to respond to a bunch of internet nobodies? Why waste your time dealing with HN's mental illness?
Anyway, hope this doesn't poison your day.
