Of course it'd be amazing if we could have frequent, long episodes but- working solo on a labor-intensive passion project in your free time between other work and life- that just isn't possible. In this case:
As a reader, I prefer less frequent, longer updates! I follow a lot of stories with short, weekly updates and it's really hard to enjoy the story when we're only getting a disjointed snippet of it at a time. It tears away the impact from the scene and I stop caring about what's happening since it's over so quickly, just for me to get tossed into another week of waiting for the next couple panels of action.
As a creator.. I'd say the same is true. I only recently began posting, but I feel that cutting down on size or quality of pages would really hurt my story. I only update monthly, but I try to make each update its own complete scene with something to add, and something of value for the readers to have waited for.
