Modern web sites often have incredibly long addresses (URLs) especially if
you go to a specific item on the site. It's far from ideal if you're sending
the address or link to a friend in a text message over the phone, or simply
writing it down for reference. Bit.ly is probably one of the best-known URL
shorteners, but JotURL is a good alternative which allows you to track how
many times your shortened URLs have been clicked. All the core features
you'll ever need are free.
