<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I use output buffering on wp_head() and wp_footer(), in order to give my theme complete control over them. Since most plugins hook onto these, they can become cluttered with scripts and CSS file links. By using OB and a custom filter, I can do things like (1) remove duplicate jQuery scripts, and (2) optimize the order that CSS and scripts are loaded in. Essentially this gives my theme the final say in what resources are loaded into the page, allowing me to "clean up after" plugins.<br>
