WordPress blog check

gistfile1.txt

//finally have a function to check if we're anywhere on the damned blog and only the blog
function is_blog() {
  if ( get_post_type() == 'post' || is_post_type_archive( 'post' ) ) {
		$blog = is_home() || is_archive() || is_single();
		return $blog;
	} 
}

One thing to note, you may want to have a return false; after the closing brace for the if statement, always safer to be explicit rather than let PHP decide.
