Isn't a user's browser technically an intermediary? The browser reads html from an initial request and makes automated additional requests for images, javascript and css files, etc and then renders the page using its own rendering engine. The only difference here is that the browser is making multiple requests and using a different rendering engine (the extension) to display it using a map. There's an obvious market for people who want the amount of data that craigslist has, but wanted it displayed in a smarter way that allows better filtering and searching. They could make a killing licensing their data to 3rd party sites (or launching a new site with an improved interface). Instead they are giving users more and more reasons to switch to other services.
