Hide Tag Input

By default in WordPress 2.3 and up, you have a tag input section below your posts, which looks like this:

Since I don't use any tags on most of my blogs, I found that tag input annoying, and wanted to remove it from my edit screen. This small plugin allows you to do that, by simply adding a bit of css the admin head, which hides the input field. Just download, unzip, put it into your plugin folder and activate, and your edit post screen looks a bit cleaner.
