Except for the fact that the Official Arduino hardware is all documented inside the site, so one link would suffice for that, why not a hardware page for "Arduino Universe" or "Visual Guide to Arduino" with any and all boards listed, with the specifications that are missing from just about everyone's boards such as size, weight and current draw. Daniel J. has already started one. The real place for this is in the Playground.
The text without links was something of utopian todo list. Or a roadmap to a (robust open-source) Arduino planet.
They could have links with question marks, that might get them one step closer to reality.
