The number of projects analyzed was not the issue, though "1100+" does add to the impression of the title being hotrodded a bit. The criticisms HN users made of the title, that I heard, were first that the paper looks only at open-source projects on Github, which is not representative of software projects in general, while the title refers to software projects in general. Second, "Why X needs Y" (where Y is a sensational word like "heroes") is a linkbait trope, easily recognized by anyone who spends time around internet articles, as well as an overselling of the finding. An analysis of commit rates on Github does not explain why, it shows that—which is great, and which we edited the title to represent more clearly.
On HN, an article does not get a pass to use these tricks just because it's a paper on Arxiv. The internet game is to inflate titles to oversell the body, and the HN game is to rejig them back to scale, so there isn't a disappointing delta between what the title promises and the body delivers. We did that in two ways: by adding Github, and by replacing the "Why" bit with a simple mention of the relationship explored by the article. I'm sure it is possible to come up with something better, i.e. more accurate and neutral, and if anybody suggests better we can change it again. But if a paper is going to play the internet game—which, dismayingly, we're seeing more of, as academics increasingly have to fight for clicks in their own right—then HN is going to play the HN game. Your authors are expert in their domain and the HN community is expert in its.
I wouldn't say this change is unfair to the authors. The purpose is to steer the thread toward a substantive discussion of their work, just what any good scientist wants, and away from title nitpicks and complaints, which is boring and no one wants. I can tell you from years of experience that once these complaints start appearing, they continue unless and until the title is edited to bring down the inflammation. We can't fight it, we can only heed it—it's a force of nature. Why would that be? I think it's that people come to HN for relief from the onslaught of bait and manipulation that plagues them on most of the internet. The implicit contract here is that the front page will be a bit calmer, more neutral, more accurate. HN doesn't do that perfectly by any means, but if it's noticeably quieter and more bookish than what is typical elsewhere, that's the main thing.
You can call HN users armchair scientists if you like, but I think you'd be surprised by how many working scientists participate in this community, not to mention many who have had scientific careers before moving into industry. They are humble and don't flaunt their credentials, but when something relevant to their work comes up they mention it, and it always surprises me how many there are. It seems a good sign for the health of the community.
