Lets think logically- you work 4-5 days a week for an entire month.
Surely you can spend 10 minutes of your time and have something to show for it, not neccasarily new features but something.
Whether its ironing out bugs, modelling, rendering, texturing, rigging, or art.
Hell you could talk forever about just those categories, not being able to add a blog every month smacks in the face of coordinating with your community.
Aint about new features, its about actually showing what you are doing, how far along are you and what is left to do.
