It would be nice if wordpress itself had the option of pressing a button saying - push to static. When you make an edit -> update static files. This would be fantastically easier + it would potentially mean 1/4 of the web gets faster overnight.
Something like call partial (list of recent blog posts) which itself could be static. Two-to-three static calls and you could have a very clean and robust system with no database queries.
oh man, that's a great idea, that would grow WP adoption rate by 1000x
