It’s a publish time plugin (like the twitter notify one), and will send the url, the title, the first couple of sentences, and any categories (as tags) associated with the blog post, straight to your delicious account.
If you don’t have it sent to automatically post to delicious, then you will get asked every time you publish a post. Also, like the Twitter Notify plugin, this will not publish it to delicious if all you’re doing is publishing your post as a draft to your blog.
