That’s all fine. But the tinyurl giveth and the tinyurl taketh away. When you encode a Web address as a tinyurl you’re hiding its target. Normally, when I read an article on the Web that has a link, I’ll hover my cursor over the link to see where it points. Even on a site with human-unfriendly URLs like CNETs, at least I can see that the link points to CNET.
With a tinyurl, I know nothing about the link except what the author chose to say about it. I can’t tell if it’s a reference to an article I’ve already read. If I want to find out, I have no choice but to click.
