The problem is that in the first page, there are three links to Ubuntu on Android, and two for the latest Apache release. Really? WTF is up with all the duplicates here?
Downvoted for being off topic. Please read the post before you comment. It talks about statistics from a symptom checking website created by a handful of medical students, using searches from Hacker News users as a sample. It has nothing to do with the Hacker News website itself.
I read the article, I didn't think you could gather any meaningful statistics from their results, because chances are, people here were just clicking things and seeing how it works. Hence the off topic comment.
