Whenever I see one of these questionable science articles jump to the front page of HN, I want to remind people that thoughtful, well-informed criticisms of said article often take a few days to appear (sometimes less, sometimes much more). By which point the original article has fallen off the front page and everyone's moved on to the next thing.
I guess my point is: don't forget that HN is just as bad (if not worse) as any other forum for promoting bad science journalism.
