Bro. You opened your account a month ago and your submissions are all self-promotional. Maybe your post didn't get a lot of votes-- but it did get a lot of comments-- most of them suggesting your claims are not credible. Perhaps all of the self-promoting cross-posters are what makes HN feel too big?

I don't know if really is size causing something to get lost. My guess would be that people really don't bother looking at anything beyond the front page.
