I agree with Morte; most of the high-level threads started in more humble beginnings and accumulated view count through many, many posts/page views. After all, both Wulf and PCat both prune their threads regularly of extraneous posts; they've both had many, many more posts than they currently have (and more posts generally = more readers, and more views).
Sepulchrave, of course, started with high level characters, but his story hour would be popular if it focused on 1st level commoners, I think, given the quality of his writing.
Also, threads with high-level characters often involve characters that have been played for a long time (not always, but often), making them more developed and more interesting to read about.
My own characters are ECL 12 right now, but they started as ECL 3. My view count is mostly just accrual from about two dozen readers who have stuck with me throughout the whole saga.
