[wp-hackers] Question about use of while in 2010 loop-page and loop-single

[Ptah Dunbar]

*<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>*

Basically twentyten checks to see if a post actually exists where as using
just the_post(), you're making an assumption that a post already exists and
it just gets straight to the point (setting up the post data globals).

The preferred way is of course actually checking to make sure a post exists
before calling the_post() to avoid any crazy, random errors that may arise.

Hope that helps!
