    I probably didn't explain myself well enough in the first email.<br>
    <br>
    We're not looking at the "type" parameter of wp_list_comments().&nbsp;
    We're looking at the "callback" parameter here.&nbsp; This is where a
    theme is overriding core functionality.&nbsp; If the theme didn't
    override this functionality with a custom function, WordPress would
    display other comment types by default. <br>
    <br>
    A plugin cannot be responsible for incorporating custom comment
    types if a theme is purposely not allowing comments of a custom type
    to show.&nbsp; There's no hook to allow a plugin to override what a theme
    is doing there.&nbsp; Even if there was a hook there, this would be a
    major problem if a plugin was changing how a theme handled the
    display of comments.<br>
    <br>
    What's happening here is themes are overriding core functionality
    without handling every scenario that core handles by default.<br>

            I believe Justin is referring to the fact that plugins can
            add the type "tweetback". If that is the case, then a theme
            that is explicitly checking only for "comment", "pingback"
            and "trackback" is missing out on the ones that don't fall
            into these buckets, i.e. it is missing a catch-all for types
            introduced by plugins.<br>

                    I can't find that 'tweetback' is a core comment
                    type.

                                        things we should be on the
                                        lookout for when reviewing
                                        themes that I thought I'd bring
                                        up.<br>
                                        <br>
                                        The use of the_post_thumbnail()
                                        with the_content() can sometimes
                                        be a problem. &nbsp;If a user places
                                        the image within the post
                                        content (at the beginning of the
                                        post) and sets the same image as
                                        the "feature image," it creates
                                        a duplicate image issue. &nbsp;Some
                                        themes' designs are meant to
                                        handle this while others aren't.<br>
                                        <br>
                                        Some themes have a comments
                                        callback function where they
                                        don't recognize comment types
                                        other than 'comment',
                                        'pingback', and 'trackback'. &nbsp;
                                        This is also the case in the
                                        TwentyTen theme. &nbsp;If you look at
                                        its switch statement, you'll
                                        notice it doesn't give a
                                        'default' case. &nbsp;It should be
                                        corrected to handle all comment
                                        types (e.g., tweetbacks).<br>
                                        <br>
                                        Loading JS and CSS on all pages
                                        of the admin. &nbsp;Sometimes, themes
                                        hook their theme settings page
                                        JavaScript and Stylesheet to the
                                        'admin_init' hook or something
                                        similar. &nbsp;This should only be
                                        loaded on the the theme settings
                                        page. &nbsp;If using the
                                        add_theme_page() function, a
                                        hook is created just for that
                                        page. &nbsp;A better hook would
                                        probably be
                                        'load-appearance_page_$pagename'.<br>
