That's excessive and starts to run afoul of this site guideline: "Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity." So if you'd please stop doing this, we'd appreciate it.
HN users, btw, are a lot fiercer than the mods about this and will use unkind words like 'astroturf' and 'spam' when they notice such repeating patterns. It's not in your interest.
