Yes, all of that is true. I for one think it's better to not put up a time line/due date. Putting up a date makes people expect an update during that time. It says "the week of the 12th" and it's now Sunday evening of that week, nothing has happened. I think it would be better to say "next page coming soon" or "next page- when we can" so that people don't get their hopes up. I know they are busy and I'm not rushing them. I just think it's better not to make promises/ deadlines you can't keep. Plus it would take pressure off the artiest as well. 
Yap, that true or giving an information that date of the next page has been changed.
Still yelling isnt appropriate why of asking :')
