Sorry to be blunt, but HN is not for proofreading/vetting/reviewing your article. You should be doing that before you post it, if you are considering it to be high quality.

Instead of posting 19 of your articles here in 49 days, my suggestion is to put more effort into fewer substantive articles. We're not writers on your staff.

and how is 19 articles in 49 days(1 every ~2.5 days) with relevant content a bad thing? Also, didn't ask anyone to write for me, just: if you dislike it, give constructive criticism and maybe suggestions

"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."
