I don't skip reading posts, but I will say that posts that are largely inner monologs I tend to skim. Unless I'm the GM or I otherwise have something to gain from reading such things. I think people monologue out of habit because it's a pretty easy way to avoid "PLAYER X IS IGNORING ME REEEEEEEEEEEEE." but paragraphs dedicated to inner thoughts can usually be ignored anyway, as they don't really influence anything going on in the RP. That, or the thoughts are so painfully obvious that they don't really need to be narrated. and in collabs when all parties involved are narrating. UGH!

	Another thing that sends me into skim mode is when one decides to personally narrate an event that was already covered in detail by other players. If you want to react in response to Janet throwing a pencil at mark's head, you probably don't have to narrate the entire paragraph long episode again. I mean, your character's only contribution is saying "Hey! pencils are for writing, not throwing!" And you don't have to be very smart to know who your character is talking to. Well, maybe you do. Depends if the other players read the pencil toss post or not. But this is why I at least skim every post in an RP.

	I speak as a player here. If you're a GM, reading everything is a must for obvious reasons.
