The author of the bottom code states that he uses the_excerpt_rss() because it "strips out all formatting tags". My question is do both codes below "strip out all formatting tags" ? What is the difference between the two codes below? Which would you suggest using?
<meta name="description" content="<?php echo strip_tags(get_the_excerpt($post->ID)); ?>" />
versus
<meta name="description" content="<?php the_excerpt_rss(); ?>" />
