There may be valid points with the going off topic, but that's every month and we probably all fall into that guilty category. Our conversations deviate and shift constantly until we actually have boxes in hand and we still digress at times. Eventually the conversation always goes back to the thread origination. People sometimes interject questions about things and they get answered by other members..
A lot of commentary would be deleted/edited just because it didn't necessarily pertain to the thread. Skim through and tune out what you don't feel is necessary/helpful. It seems unnecessary to blatantly censor/edit because someone doesn't want to see something.
Plus, we have great mods!
