https://launchpad.net/bugs/685380 is a bit tedious, and it uses up a fair bit of space in a microblog entry. You can use any of innumerable URL-shortening services, but then the URL’s opaque; which is a shame since it really just wants to represent a 6-digit number.
Therefore: pad.lv (pad love), transparent short URLs for bugs, and other things including projects, people, bug-filing forms, packages, and more.
Maybe someone would like to make bookmarklets that generate these links, or add them into the Launchpad UI?
Thanks to Latvia for letting us use a fraction of their domain name space!
