I think I read some days ago another stat, that the average rating of “Show HN” posts is going down. So the pessimistic take is that people feel the bar to present their product in a “Show HN” is lowering.
(edit: striked) <strike>Is it deliberate that this post appears as “Show HN” itself? I hope not to be too negative, but to qualify as such I would expect much more that a page with two graphs.</strike>
I can edit the post and delete that part, but this would make OP's reply seem out of context. But HN markup does not support striking. I put some HTML tags there anyway, the sense should be clear.
Just mark your edit 'edit:'. I often have the same happen where I write a comment and then think 'oh, that's no good, I need to improve on it' and then in the meantime multiple people will comment and hopefully quote the original. That way at least you can see what they replied to rather than the version that I'm finally happy with. I've suggested HN increase the default size of the reply box but so far no takers on that.
