This site destroys the community spirit in the internet ...
it makes communities anonymous, u dont really know the nicks of the people u r interacting with, their track history on the site, etc. ... its good shallow questions, but then it basically replaces community sites something went wrong ...
and u get thumbs up if you praise something about the community, any critcial replys not praising something will get downvoted without an answer as to why ... its like "oh, u r against me => insta downvote" ... to some degree this also mitigates critical thought, because u dont want to get downvoted by the hordes of fanboys
