I kind of wondered the same thing myself... the only reservation I have about having a strict posting order is that the story could get hung up for awhile waiting for one of us to post.  I know I don't get to all my stories every day and I would hate to keep you guys waiting because it's my turn and I didn't have time to write, you know?<br/><br/>Personally, since it's just the three of us, I would prefer to keep it more casual, and we post when our characters have something to do/say.  And if our characters are feeling left out, just say something OOC.   I'm sure it would  never be intended, and if it happened,  we seem to be a nice, cooperative group, and would fix it as soon as possible.
