Here’s a web service I’ve always valued: TinyURL.com.
Have you ever wanted to send a web link to somebody and discovered that it has a long and unwieldy URL like this one?
It really messes up your email formatting, some email programs fragment it so it isn’t clickable, and it’s impossible to dictate to somebody over the phone or to send in a text message.
If you hop over to TinyURL.com, though, you can just paste it in and get back something like this:
which does the same thing and is much easier to hand around.
There are other services like this, but TinyURL has been around for a long time and seems to do a good, efficient and quick job.
