So the agreement seems to be just because the character interaction doesn't involve yours allows you to dismiss it as unimportant (as per the OP), but that also 'you must read all posts' (as per some of the immediately following comments) has certain conditions that I think have been well documented. I'm glad there has been some clarification and discussion from some of the earlier posts. Made an interesting read at least.

At least for the most part, 'you should read all posts on most threads and most posts on all threads' has held true.
