yeah, thats what I do!!!
If you are active on twitter or other such similar sites, then you would definitely be involved in shortening url’s quite often to post them in your updates. It gets a bit tedious to visit a url shortening service each time to shorten a url.
Here is a great plugin for Mozilla Firefox which you can use to conveniently shorten a url using the is.gd service.
