Guess the questions is, what determines if you've "added value". Certainly there is value in adding to information (said article talks about Y, but you might also want to consider Z depending on your application), but there is also value in adding entertainment (at least the RIAA and MPAA think so), and even a well executed troll or Meme addition can be of some value to some people. So I wouldn't presume that you are not adding value unless you just enjoy putting yourself down (in which case you are still adding value to some folks I am sure). :-)
