Tracking revision history is one of the hallmark features of wikis, but what about non-wiki websites?

On The AboutUs Weblog, Tak Kendrick writes that a Portland, OR based company called Versionista has developed a tool that can track changes on any website, and show you what’s been added and removed. Here’s an example of the revisions tracked on Versionista’s home page.

This is an excellent service for all the websites that aren’t – and don’t necessarily need to be – built and maintained using wikis. Revision history can be used in a variety of scenarios. Here are several examples from Versionista’s press release:

• “Job Openings” area – to show seekers what’s changed since their last visit;
• End-user license agreements – and other Web-based contracts, to visually show exact changes;
• Product and service feature pages – to highlight growth of product value;
• Government pages – to detail legislative history and revision of policy and other public documents;
• Internal Web projects – to allow editors to archive and follow development over time.
