PLOS one and PHD Comics

I don’t know the idea of the peer-review process of PLOS One until I saw this comic on PHD Comics (you might need “something” to view this site and the comic above if you’re in China). And on PLOS One’s site, it is said that “PLoS ONE will rigorously peer-review your submissions and publish all papers that are judged to be technically sound”, and they won’t make a decision on a paper based on its “interestness”. If this is the case then the possible impact of the journal on science might be questionable as the quality of the papers published on the journal could be vastly different, which could lead to a downturn for the willingness of people to submit their possible high-impact papers to the journal especially as you need to pay for the paper to be published and in case that this journal doesn’t have an IF.
