At
the Documentation page, there is a whole bunch of really interesting pages, and also a whole bunch of "Not Ready Yet". I would love it if Wolfram could provide an RSS feed of the changes to the documentation as they happen. (I'm thinking more of an automated diff-finder than a blog.) The example from the top of my head is
www.gwern.net - a really interesting site (with which I have no affiliation - just an example of a site that does what I'm thinking of) which provides an RSS feed of every change Gwern makes to it.
Of course, the architecture of the documentation site might not easily allow for this - but then again, presumably the engineers are using some kind of version control, so half the work would appear to be already done. Gwern uses
Haskyll, which is an existence proof for the concept.
