Here's my first attempt at a Ubiquity command. It's called twituser and (for now) just opens up the website www.twitter.com/ (not very useful, as the email announcing new followers already contains the link). Next step will be to have it preview the summary info for the user (how many followers they have, etc).

The other command (verb) is is.gd and it's just a copy of the tinyurl one but using is.gd
