Argh, I didn't really like to see the "Here's my new app" at 4/5 of the article. I understand that opportunist people like to leverage situations.. but I don't like the fact that this article has been ranked first on hacker news. I mean, the first reason I go on HN is because of the "Smart Filter". More precisely, I have trust in HN users that only good articles are shown. (Like I try to only upvote good articles thinking that other HN will like them). I'm disappointed.
