Not to do so much with posts being readable but being able too read between the lines so to speak, sarcasm is really hard to translate to written word.

IRL (In Real Life)(#sarcasm), I use dry humor, light sarcasm and been dubbed the King of the backhanded compliment by people who I talk to. Be that as it may, very difficult to do that in writing, it will come across as superiority, ego, anger, when trying to convey the polar opposite. So much of how we are interpreted by others when we use sarcasm is based on factors that are not able to be interpreted in writing such as syntax, body language, innate familiarization of the topic, inflection.

Something to also consider.
