TextMate has a basic, built-in blogging bundle that provides some decent features. You can use a variety of syntaxes (HTML, Markdown, etc.) to pen your next digg-worthy post, and the bundle also has rudimentary support for retrieving posts from your blog to edit. It's not bad, but it isn't stellar either.

Todd Ditchendorf's BlogMate plugin, however, is stellar.

As a blogging interface for TextMate, the first thing you'll notice is that BlogMate isn't simply a bundle - it's a full-blown plugin, offering a palette with all sorts of control over your MetaWeblog-compatible blog (for now BlogMate has only been tested with WordPress, but in theory it should work with any of these blogging systems). As you can see, BlogMate can keep track of a configurable number of past posts, hook into your categories and even display previews with pictures of your posts. BlogMate can also handle multiple blogs for those who can't stop at just one (I'm looking at you, Scott McNulty).

Setting up BlogMate is a breeze, though I should probably mention at this point that it is a beta product, so I echo Todd's sentiment of backing up your blog's database just in case. Creating a new post is as easy as opening a new TextMate document and typing away, but there's a major difference from the Blogging bundle here: you don't need to insert a post title; you do that when you actually finish the post and click BlogMate's 'Send Post' button.

Managing posts is one area where BlogMate really shines, as editing a post is as easy as writing one - simply double-click any post in your list (and you can configure BlogMate to pull down more than the default 10 posts) to open it with all formatting preserved. Deleting a post involves nothing more than selecting a victim and pressing delete.

While you don't get some of the finer features of other blogging clients, BlogMate is already a pretty powerful plugin for the rocking swiss army knife text editor that is TextMate. Todd has done a great job here, and I hope enough interest builds to help make BlogMate worth everyone's while.
