Reddit for WordPress Plugin

/ Published in: PHP

This is a terribly simple but useful WordPress plugin that puts an interactive counter-style Reddit interface on your blog — but only when someone has already bookmarked the URL. It looks rather lame when everything isn't bookmarked, but the JavaScript interface with the arrows is a definate enhancement over a simple icon. So why not show it only when applicable? I'll narcissistically bookmark this post to demonstrate. Just call the function "reddit_this()" and specify one of the styles enumerated here (http://reddit.com/buttons). Enjoy!
