Eh, I'll admit it and not even feel bad about it. In a large RP, where things are well separated, I read post that are related to the area where my character is, and relate to his character. If a post is in some distant land with a character I've never interacted with, and probably never will interact with, and is a different group we're not fighting, I just skim it for important information. I chose a following of characters anywhere remotely close to mine, or people's I just plain like to read in depth.

Now in smaller Rps, I wouldn't even imagine doing that. Everyone is just thirsting for a chance to interact, it'd be unfair to do that.
