Vimcasts.org now has it’s own short form URLs. You can link to each episode by
number, using the form
/e/10 to link to episode 10. You can also link to the
episodes archive with the trailing path
These short form URLs are perfect for sharing on Twitter, and in other situations where characters count. At the end of each screencast, I can now include a short form URL so that you can easily find the corresponding show notes for an episode.
