But I would encourage folks to consider their approach, in general, whenever we are in a professional context (and, despite the casual nature of HN, this is very much a “professional context”).
I think that some few people here, are able to post in a truly anonymous fashion, but most folks could be doxxed fairly easily, if they piss off the wrong people (not always movers and shakers; we have some truly amazing talent, hereabouts).
In my case, I just make it clear who I am, and post carefully (I know it may not seem so, but look closer). I learned, long ago, that I’m not actually able to maintain true anonymity, so I don’t even try.
