Thanks to Robert at Stack Exchange, Jorge and I now have access to @askubuntu on twitter (and I'm going to email the other mods with details here shortly).
Something that was mentioned at UDS-Q was that @stackubuntu was "weird". Should we formally request that Stack Exchange rename @stackubuntu to @askubuntu?
It's already been done for Apple.se, so I don't think it should be that much of a issue.
