When I was back at Blogspot, none of my posts had titles. There wasn’t even a textbox to enter one – I assume I’d unknowingly disabled it. When I moved over here to WordPress, I imported all my old blog entries, all of which were then posted with blank titles. Makes it a little difficult to search for entries.
So I added titles. And tags. To every single post. Even the stupid ones about articles that almost certainly don’t exist anymore.
