Well, you should work on statistics and what not, seeing as most of the services that people really use have in depth (or as in depth as possible) statistics on where the traffic is coming from, how many clicks, where they are, etc.
Also, you should really work on the theme. I see you say "If this theme is messed up, please use firefox as this is ideally made for firefox." and, well, it isn't really that hard to make the theme cross browser compatible, or at least, move the message to the bottom of the page, much smaller, as to be honest, I couldn't really care what it was made for, as long as it works. Lol.
Also, you have some issues with the message after creating a short url:
Short URL has been created!
The following URL:
http://www.google.com
has been length of 21 characters and resulted in the following shortened URL which has a length of 15 characters:
http://ex8.me/N
Should be more like:
URL Shortened!
The URL "http://www.google.com" has been shortened from 21 down to 15 characters with the shortened URL "http://ex8.me/N".
or something like that.
