One thing I don't like to do is have my character go back in time to respond to someone's last post. I prefer to have the flow of time continue at a usually rate, which is why I don't mind short posts while 2 characters are interacting. I'd rather finish my post with a question so the flow of time isn't disrupted.

Time skips are another thing I feel like I'm the only one initiating in some of my rps xD
