A few things I've noticed so far:

- Broken link: http://d-apt.source-forge.net/
- Link to redirect: http://www.dlang.org
- "D's standard build tool is dub." I think rdmd holds that 
title, Dub is the de-facto standard package manager.
- Would be nice to make the back/forward links bigger, so it's 
easier to click them. Perhaps put the name of the target page in 
the links.
- "Import's & Modules" - not a contraction, no apostrophe.
- The wording could use a do-over in places.

Perhaps put the content on GitHub to allow easily accepting 
contributions?
