Based on twitpress by Tom Purnell. Adds the ability to choose which category will result in updates to your twitter account.
TwitCategory sends a tweet notifying your followers that a new post has been published on your blog. It is very customizable, allowing you to format the tweets using static text and several variables: title, post, permalink, guid and category name.
New versions also allow for URL shortening via tinyurl, isgd and bitly!
