If you don’t find using the default post editor in WordPress very efficient, or for whatever reason just want to be able to post to your WordPress blog without going to the admin panel, starting a new post, and going through the somewhat lengthy process of getting everything ready to go, then they are quite a few alternative methods to getting something posted.
Bloggerdesign.com currently has a great list describing many of them, including a fairly good list of desktop applications or browser addons.
Here’s a taste from one of the methods they discuss…

Press This is a bookmarklet that you can add to your browser. When you find something you want to blog about, select it and click the Press This bookmarklet. It’ll then open a small WordPress post window that is auto-populated with the selected text and allow you to put the finishing touches on the post.

Out of all the different ways I’ve tried in the past, that I like ScribeFire the best, but it really comes down to personal choice, and what you want to do with it. There are certainly enough other options that if you wanted to you could avoid the default editor forever and no one would be the wiser for it.
Are they any methods that people are using that weren’t included in the list? Let me know what you’re using in the comments. It’s always interesting to hear about how people are using the different tools available (or creating their own).
