Thanks for the clarification. I guess I was wondering if the adding of new features & function took away from the simplicity. I think thats the challenge for both Posterous and Tumblr: satisfying existing users while still making the end product dead simple for new users (e.g. my parents).
I think Posterous is actually pretty good with adding features so far. Last I checked it was still dead simple. So's Tumblr, I guess, but now it FEELS more cluttered. Like it's doing more than it ought to. Even though it's still point-n-click, the page is more distracting.
