Now I know why WordPress doesn't allow to list/delete big chunks of posts
 

Just because it's tooooo fuckin' slow! I've just completed coding duplicate post removal script which will be a part of CyberSEO package (it will be available again for purchase very soon) and I can admit that calling almost any standard WP API function takes to much time.

Huh, I love WP because it has lots of good features. But the ppl who coded it have no clue what code optimization is :disgust

The one thing that really sets me back in WP, is the way it will butcher code, sometimes, when switching from the html writing mode to design.

grrr....
