Not an automation issue. The pages have to be uploaded, just as any comic site has to do. We can specify whatever date we like for a page to be viewable. We went with the multi-page release once a week approach because everyone else was doing one page a day, and we wanted to see if we would attract, and keep more readers if we did it this way. Our readership retention seems to be pretty good. However, search engines do favor sites which change daily. It's an electronic world, and we could easily switch to whatever release schedule we like (as long as we have the completed pages uploaded of course).
Like much on the web, don't be surprised if we change things up from time to time. To that end, input from our readers is important, so keep those comments coming!
