I know this is the Internet we have to live with, but this kind of stuff just makes it a worse place to be.
I see this less as "gaming HN" than "realising what the niche is" and fulfilling the niche. I guess I'm fine with someone posting first about a subject that will be there anyway? Maybe I'm not seeing something.
I read the article in the spirit of the headline, which is basically: we wrote a bot to tell us stuff that would do well on HN so we can shill our/our clients’ stuff. In other words, HN becomes an echo chamber of rephrased news articles recycled into commercial blogspam.
