Excellent service. The only suggestion that I have... Is that you center the design (i.e. use percentages, instead of fixed widths).
So, I think it's only fair that twitter users have the ability to see whether or not a link posted by someone they are following is an advertisement or not. This includes TwtAd ads. TinyURL is the main short url service used on Twitter and although they do have a feature you can use to see where a link redirects to before going to it, not a lot of people know about that.
I've developed Show TinyURL, a site you can use to find where a TinyURL link redirects to:
Show TinyURL - Show Where a TinyURL Redirects
I made the design of the site based around the design at TinyURL. I used all the same colors and worked around the simplicity of it, but gave it my own flavor.
I used AJAX to make it really simple to use
What do you think?
It's very cool, but I'm asking myself atm why people don't copy the link, and just put 'preview' between the http:// & .tinyurl.com, it gives a preview of the link too
What you could do to make it more special, is post a screenshot of the website after it is 'checked'. Otherwise I don't see many benefits of using this site instead of using the subdomain preview... The preview can be done by websnapr - Website Thumbnails For Your Site
Instant Messenger Bot
I developed a simple AOL Instant Messenger Bot last night that does the same thing as ShowTinyURL does. Send him an IM with a TinyURL link and he'll tell you where it redirects to
The screenname of course is ShowTinyURL.
I will be offering this bot on most popular IM clients.
I now have a bot on MSN to. IM email@example.com
