[wp-hackers] Minify Scripts and CSS and why it isn't completely possible

[Vladimir Prelovac]

Jacob I must have missed something, but you seem to be referencing a 
different plugin from PHP Speedy, possibly your own. Can you send more 
information ?

If you have combined scripts that are correctly using the API that would 
be great. In combination with putting the code to the footer will 
greatly increase the performance ( I released a simple Fotter-javascript 
hack a while ago 
http://www.prelovac.com/vladimir/wordpress-plugins/footer-javascript )

Regarding WP_Styles the main problem that is turning people off from 
using it is that wp_print_styles is still not happening automatically 
(like wp_print_scripts in wp_head) but you need to call it manually 
(this goes from my memory and I think it's still not fixed in 2.7).
