I realize that's not what's being claimed here, though.
There's no intrinsic meaning to how stars correlate to quality is my thinking here, but perhaps only due to familiarity do we think that more stars is better and not worse.
Kubilay Tekin: I hadn't gave 1 star just because I want my comment gets shown on top, I actually think that the game is aweful aqws.w.wew..ws
(I've seen this phenomenon before - there are quite a few who associate 1 with first place, hence surveys and such often have the [1 = worst, 10 = best] next to each "rate xxx on a scale of 1 to 10")
He is saying he hasnt only given 1 start to be at the top, he actually does think the app is terrible
I've never seen an online 'stars' system that works that way... but it's possible in some other cultural context a single star is somehow honored more than many, and thus without explanation the star-system could be misinterpreted. (Of course the comments here strongly suggest that's not a factor in this case.)
