I read your instructions on removing a side bar with great interest. I see that by changing things a bit it could remove a side bar from all pages other than the home page. This seems to be an alternative to the css two style sheet method using different Thematic layouts that I have just implimented on a 'blog' with WP being used mainly as a CMS.
What are the advantages & disadvantages of using removal of a side bar using your function as against using pure css for not displaying the sidebar?
