Stupid people posting stupid posts about stupid people posting stupid posts. How stupid that is?
Time from time, people probably have to prove something to the others to feel better. A lot of them often have nothing to prove it, because they're simply not doing anything interesting. So they at least try to act a like they're better person than everyone else.
If you have account with at least few friends or people you follow on Facebook, Twitter, Tumblr, G+ and/or another social networks, you surely saw (or even wrote) at least one post about "the other people" posting and sharing crap.
The question is - what makes your actual post about this fact not a crap ? It's the same like whines about the others taking and posting stupid photos or videos. You're only writting it to get attention, you're missing so much.
