Also learned about the W3C’s Log Validator today. Sounds like a really cool tool.
According to their site, the tool takes a web server’s last logs and processes it through validation modules. Those validation modules check the most popular documents’ validity for a certain technology, like (X)HTML validation, for example. Doing so helps me find the most popular pages on my site that are invalid, and thus tell me which (invalid) pages I should fix first.
I’m sold. One more thing to add to my “How to Fix Lambda Chi Alpha’s Web Site” list.
