blindRSS is a very simple browser-operated RSS reader. You can click through the feeds in a sidebar, use the (hopefully self-explanatory) icons next to them to manipulate them, and do all the other stuff a RSS reader should do. It's programmed so that the feeds are reread by a cronjob or daemon, while as much functionality as possible is done within the client. Thus, the server only serves the data, not the markup.
The objective of the NIST Web Metrics Testbed is to explore the feasibility of a range of tools and techniques that support rapid, remote, and automated testing and evaluation of website usability. There are currently six components: 1. Web Static Analyzer Tool (WebSAT): checks web page HTML against typical usability guidelines. 2. Web Category Analysis Tool (WebCAT): lets the usability engineer construct and conduct a web category analysis (card-sorting). 3. Web Variable Instrumenter Program (WebVIP): instruments a website to capture a log of user interaction. 4. Framework for Logging Usability Data (FLUD): a file format and parser for representation of user interaction logs (such as those captured by WebVIP). 5. VisVIP Tool: produces a 3D visualization of user navigation paths through a website, based on FLUD data. 6. TreeDec: adds navigation aids to the pages of a website.
