First of all, you dont quote a post which is above your post.
Second, if you quoted me to indicate that your post is an answer to my post then I dont care go whine somewhere else, what are you 15, 16?
It was said numerous times.
If you liked posted pics,vids, you can say it was funny shit, good finding or something like this, to motivate poster in further participation.
If you dont like you no one cares about it just stay quite and dont post stuff like, your sense of humour sux, Fail, you are not funny go killyourself asdfasdfasf, or some other shit.
Now when you know how its work maybe social interactions will be easier for you
