doiop.com: This is a play on TinyURL, but you get to choose the keyword that makes the link.
Some web addresses (URL) are very long and complicated. doiop creates for you a short URL with a keyword you choose, making it easy to remember or give away. This link will not break in emails and never expire.
For instance, I made this link using the keyword “gadget.”
One extremely obvious problem: they’re going run out of keywords. If this takes off, they probably have one month worth of keywords before people are going to start getting really frustrated trying to find one that hasn’t been used and quit.
