Should I notify everyone when a chapter becomes available? (Patreon)

So as I work out the kinks of the new  reward tiers I've realized that when I make a chapter available to the next tier down (IE when a chapter that was once only available to Board members becomes available for Investors) I could notify everyone of the change, or I could let everyone do it on their own so I'm not stuffing peoples notifications with a bunch of updates. I'm going to leave this poll up for a week, so let me know what you think. Rather than make a judgment call I'd like to hear what everyone thinks. I will use the notifications until this poll is closed after a week.
