I think readers have it tougher because creators have more control over the work that they do. Readers really are at the mercy of a creator's schedule. That creator may be exhausted one week, go on a vacation, be caught up with work or school and so on. Sure as a creator, I want my story to be read and enjoyed but creating the page for the sake of creation already gives me a lot joy. There are web comics that I've been reading for years without any payoff in sight. Some cool series I've invested in just stopped because the creators had no more money, or time, or jut decided to move on. In the creator's mind, there is a complete picture of the story. Not in my mind as a reader.
It's tougher to wait as a comic reader!
