I'm playing around with a new feature in the server.
If it works, when you click on this: blog.1999.io -- you should see what used to be at a much longer url. And when you click on the longer url, that might already be linked to from a variety of places, you are whooshed off to the short version.
I found a neat way to implement it, just wondering if I thought of all the problems that could come up.
Update: Here's the howto for this feature.
