All right, this is a cool, but why do comments have to be exposed for this button to show up? With both of the templates I use for my blog, it says X comments, and you have to click to see them (I am not a fan of this, btw, and wish designers would lose this idea, and just leave comments exposed). Only then does the Tweet button show up. Why? I want the POST to be retweeted. I don't care if the comments are. This is also the case with http://lionseye.wordpress.com.
Also in the main blog linked above (not Lion's Eye), the like button isn't showing up, even though it's checked in the Extras menu.
And what about the FB like button tie in? Type Pad and other blogging platforms have that. Why doesn't WordPress?
