(That said, I almost never downvote.)
I don't think it works exactly the way you think it does.
I will add that being the first woman on the leaderboard is not essential to the point that you can get a lot of karma and not be part of the echo chamber. But inevitably that is the detail that gets focused on, as if proving that I am not the first woman (or questioning my assertion, because no proof to the contrary has ever been offered when I get asked this) somehow invalidates my actual point.
My other handle has 25k karma. This one has over 3k. I don't in any way whatsoever participate in an echo chamber.
If it's not essential, and you don't want people to focus on it, why did you bring it up? It was the only interesting part of your comment (to me). I don't really care if HN is an echo chamber or not.

I actually dont care if you were or were not the first woman or if it was someone else, I was just curious about how you knew on an anonymous forum. But go ahead, be mad about it.
Your blog post is interesting, so thanks for linking that.
If you want a community that is hard to get started in look at StackExchange. You can't even comment until you've gotten quite a few points.
One reason for me to stay here is the diversity (and civility) of the comments, I don't think it's too bad. Another favourite read of mine is Arstechnica, but the comments there don't reach the quality of the comments on HN, imho.
