[Cutts] also talks about including access to information that isn't otherwise generally available. Here are some ideas on how you can make it quite different:

  1. Recognized Expert Analysis: In addition to producing the list of resources, add commentary and analysis from recognized experts and cement that with rel=author tagging. This is where the "editorial voice" and "distinctive point of view" come in.
  2. Unique Expert Reviews: Include expert reviews and commentary on the curated content. The key here: these reviews aren't published elsewhere. Rel=author tagging is a good idea here, too.
  3. Data Sources: Accessing data sources not available to Google is also useful. Bear in mind, though: it's critical that these data sources be very distinct and differentiated in a way that will be immediately obvious to both users and Google.
  4. Freshness: If you have a method for updating this in real time, and significantly faster than Google does, this may work as well. Note: a regurgitated news feed fails this test.
