I don't see Steem the blockchain as a mere blogging platform at all. To do so would be incredibly narrow-minded. Sure, you can implement a daily post number cap at the front end level but such limitations have no place at the level of blockchain rules, in my opinion. Why? Steem should be a universal content delivery platform with rewards, open for app developers to develop any type of app they can possibly think of.

By the way, the payout window limitation has already been worked around with Steem Forever.
