fiskeben

Adds a link to each post that points the user to Twitter.com. Before the redirect, the URL for the actual post is sent to Tinyurl.com and the tinyurl-ified URL is used as an argument to Twitter.com thus putting it in the status field when the page loads.

FishyTweet

Adds a "Tweet this" link to posts, shortens URLs with tr.im or TinyURL and sends the user to Twitter.com.
