I'm not sure what aspect would be so changed (?), as threads are already swapped out more frequently than each month. It wouldn't be different or need to be more frequent than what is done with OT and Weather threads that go long, for example, so I'm not sure why it might be seen by some as something negative. New thread breaks don't decrease or limit the number of pictures that can be posted, it just makes it much easier for all members, new or veteran, to access and see them.
I do hear your pain, though, at any change that is discussed if its something that people are used to on a particular topic, even when it would just be a duplication of what is already done elsewhere in the same forum.
