Formating Issues

I just spent the last few hours formatting my last post so that the text would have the same spacing as every other post I've ever made in this blog! When I first published it earlier today it was all squashed together. It was still legible and all, just not very clean looking. Most annoying. I seem to have finally done something to put it back the way I want it, but I'm not sure what that was, or how I could do it again.

Most annoying.

Edit: I've just realised that the vast majority of you read my blog through Google Reader and wouldn't have noticed the change, as Reader uses it's own formatting for text! Hah! Still, at least it looks nice on the page now.
