Quite a while ago, Neil Moffat started the Delphi Basics site.
It is aimed at beginners, but since it has such a wealth of information (for instance a comprehensive list of compiler directives).
So even if you are a Delphi pro, it is worth to give Delphi Basics a look.
The cool thing: Neil originally is not even a programmer, nor a writer.
Maybe that is his strength: he learned by doing, step by step, now giving us a peak on what he learned.
