Then you'll probably appreciate the following info. You have commented excessively on HN over the years. If you have done any publicly accessible writing with your real name attached, then it is quite easy to find out who you are by correlating writing styles. (If you don't have done so publicly then at least your employer will be able to do that using all internal writing on one hand and all your HN contributions on the other.)

Sounds far fetched, but it's really not that hard. Quite recently somebody hacked this for correlating HN accounts with each other and found alt accounts of people with high accuracy. Which people confirmed. And that wasn't even a serious attempt, just a little hack on a sunday night.

In a sense, it's all too late now since all your writing is already out there. But could be good to know for the future.
