No idea. I run without SK2 and don’t have that behavior.

Yahoo being ding-dongs? Seriously, if your feed is okay it’s just a matter of the various syndication sites updating on their schedule. They all have different ones.

Ew. Yeah, that’s likely the problem. See, if I pull your feed directly from the wp-rss2.php file, it looks fine. But the redirect — which goes through the root index.php — is toast.

That index.php should look like so:

<?php
/* Short and sweet */
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
?>

And that’s it. You’re actually not even getting to your theme’s index.php. The root one is merely a kicking off point and shouldn’t contain any of your “content”.

Hadn’t seen that, but it’s nice.

In terms of the Gravatar preview, as I commented on that post, everything he wrote is immediately and easily applicable to WordPress. I have it in my comment previews as we speak and it took about a minute to do. He came up with a very slick way of doing it, I’m impressed.

Plugin in progress (for paging if nothing else).

Doesn’t appear to be a way to do that short of editing the core, though you could write a plugin that provides a new function just like it that simply inserts the character you want.
