Up to now, I've been updating Monday, Wednesday and Friday. To be completely honest, I've hit a string of zones that I don't particularly enjoy, so I've been rushing the quests given to me, and only collecting screen shots for a couple chains.
Until I get to zones that I'm more prone to take my time with and fully document, I've slowed down the posting schedule so that I don't run out of material before I have more ready.
For now, updates are once a week, on Thursdays. When I have more of a buffer, I'll increase it to Tuesdays and Thursdays. We'll see where it goes from there.
