I am not sure what you mean.. I don't think I even ever read a "tell HN". I'd probably feel weird to step on the soapbox that way.. but feel free to elaborate (or do whatever you want with any of my posts, for that matter :)
A "Tell HN" is like the selfpost (if you're familiar with Reddit) of Hacker News. Instead of posting a link you post some text.
He was suggesting that your comment is good enough to be posted as a standalone entry on here, if you want to do that go to the top and click "Submit", the rest is pretty much self-explanatory.
This is my first account of like 10 that lasted a few months before getting hellbanned, so I would feel more than a bit presumptous doing that. I'm glad a way to behave a little, so I can occasionally rant and get heard, or simply add things I know to a discussion, or upvote comments etc., but personally I am so far left leaning, and not even a professional, but "just" someone who has been into computers since he's a kid, programs a little and loves the web, that I'd seriously feel weird making an "announcement" like this, and tell others what their duties are. Am I a coward, or does that make sense?
Not that I want to diminish my post, I stand behind every word, but I also put "we" in quotes because of the above, because I really mean you guys, the people who really know their shit, the people who don't feel helpless when confronted with math, the people who build the tools I use and write the code I learn the pitiful little things I know from, the people who stand a snowball's chance in hell to ever get hired by any of the agencies or corporations that do these things, because I really don't, you can take my word for it. When it comes to democracy or philosophy, all are equal, and in that sense I'm do not want to shrink from anything; but when it comes to HN per se, I do not consider myself a peer (this time that's a compliment) and do not want to pretend I am one, I get carried away enough as is sometimes ^^
