HN is a very nice place that I feel bad telling people about it just to come and ruin it like many Internet forums I've seen in the past. From all the people I know there are maybe 5 that have a place here and most are already long time readers.
I'll talk about it in person with people I know at work or I'd mention it on my old blog - but I don't want to risk it to the "unwashed masses".
But maybe I'm being too cautious - it is pretty in-depht here. That alone might dissuade most of the shitposters. And the karma-requirements for downvoting seem sufficient.
