I like being able to complete a scene or bit of character development that I've started, but sometimes my posting frequency doesn't keep up with others, least so far in the one other game in which I've played.  So having a way to catch up in my character development without dragging others back in time appeals to me.  I've not scened in IM before, but like the idea as long as it doesn't become too frequent that others start to feel excluded.  As long as we try to write together as much as possible as a group, which is the true purpose behind the plot idea, then I think the occasional IM interaction between two individuals will be okay.<br/><br/>Fuzzy time confuses me, but I'm relatively new to this so can't really give an experienced opinion on it.
