I'm looking for an alternative to the Distill Web Monitor. I use it to watch web pages (via specific Div elements) which don't supply an RSS or Atom feed, and therefore can't add to Feedly.com. For my usage I can't justify the prices Distill are trying to charge, and want an alternative - preferably open source.
I would prefer a desktop application for Windows, or a web app. I'm a developer by day so open source projects suggestion are also welcome (i.e. something I can contribute to or at least compile).
