It seems the Stack Exchange community as a whole "really, really hate" URL shorteners (source).
But what's our (Ask Ubuntu community) stance on pad.lv, the "site-specific redirection service for Launchpad.net"?
I found this service pretty useful while posting a link to a bug-report in Comments section, for example, https://pad.lv/1532508 works well in place of https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1532508.
see [this launchpad bug](https://bugs.launchpad.net/…), where there's no difference in the output. Is it the comment's character limit or the actual output you're worried about?
