On a side note, blizzard really makes us go great lenghts just to for example make the world map quest icons show on the minimap. That's what I used Astrolabe for until Cataclysm came, so I am researching for alternatives. Preferably a library that let's me just tell it "show X on the minimap" and it handles orientation and position of the icon itself.
By all means share your knowledge, I like to learn and discover new things -including new libraries.
