It's awesome how you can stumble upon sites that are so funny or interesting (in multiple ways) that you just want to share them immediately forward. Everyone says it but it's true: something just got lost in translation when social media pages ate the whole internet.
My theory is that it's that on many of these sites there's no easy way to comment, like or otherwise publicly interact. Sure you could try and email the person but that takes effort and you have to talk directly to them, not to a crowd.
When you don't have to worry about a mob of negativity, you can write far more freely.
