The url has become an important part of lives, when it is shared around. You want to have a Get, not a Post, and the url has to include text for the SEO, but should be easy for human to make mistakes.
I love Stack Overflow’s URLs. Here’s an example: https://stackoverflow.com/users/6380/scott-hanselman
The only thing that matters there is the 6380. Try it https://stackoverflow.com/users/6380 or https://stackoverflow.com/users/6380/fancy-pants also works. SO will even support this! http://stackoverflow.com/u/6380.
Great post here with Scott Hanselman:
