The Danger of Link Shortening

Bit.ly, tinyurl.com, and many other places have started up link shortening which is usefull for Twitter, telling people over the phone, etc. But what it makes difficult is the fact that you have no idea where that link is really pointing to. As we can see from this post here, there are dangers with the way that Mozilla handles URI's. You could exploit those dangerous problems with a shortened link, and nobody would ever be the wiser.

I'm not saying that we shouldn't use link shorteners, but we should have some way of making sure we actually want to go to that place. Security is a big problem when you shorten links. So be careful when you actually go to those links, eh?
