Speaking of Rapid Development... There's a protocol called pubsubhubbub by which your blog can tell the world that it's updated. Usually when I hear the word "protocol", that means "oh man, complicated." But I got my new thrown-together blogging software to use pubsubhubbub while I was riding the bus. It's not that I'm brilliant. It turns out that pubsubhubbub's pretty simple if you're just managing one occasionally-updated blog.
