The custom matcher idea for technologies is really cool. I was thinking about doing a similar thing, but as an open source project that people could contribute matchers - but your approach is a lot easier for people to contribute. Think there could be a problem where people might not want to contribute when they can't use what they contribute outside of your system. Have you considered extracting the matcher into a gem (or _your language equivalent_) and allowing people to use the matcher? Might not be the best idea because it opens up competition, but if it became the defacto tool for analyzing sites, there would be a lot of trust back your way. On a side note, if this was an open library, or you did have an API to pull information, I'd contribute and definitely use it on a site I recently built ( http://lineofthought.com/ http://lineofthought.com/ ).
