Cite Bite allows you to send or post links to a specific section of text on a web page. Hmm. Sounds like debate evidence to me.

I can imagine creating a unique URL for every piece of evidence so other people can quickly find the original quote. Here’s a sample link:

It doesn’t work exactly right if you are trying to include multiple paragraphs and it obviously won’t work for sites that have dynamic URLs.
There isn’t much information on the Cite Bite website, so I can’t determine the uniqueness or permanence of the URL. TinyURL, for example, creates permanent URLs for sites and multiple submissions of the same URL received the same tiny URL.
