"One of the purposes of voting/liking is to provide a *quick way** to engage a post without the full steps of writing a comment."*

People who can't be bothered, or are not capable of writing a proper response should be discouraged from interacting with a discussion topic, not encouraged. The upvote/downvote system is probably the biggest insult to intelligent debate that has ever existed and is not only perfect for shills, brigaders and forum sliders, it also gives the redneck with an IQ of 75 the same level of influence over the readability of a post as the intellectual who actually reads the post and the linked material and writes a thoughtful response and this surely is the reason so many reddit subs are little more than meme fests for the sheeple. Discussion topics for the intellectally challenged. Just look at the image, if it makes you go "hur...hur...hur...hur I agree with that", click upvote, else, click downvote. Well done, you just took part in a discussion, now scroll down to the next meme and repeat.
