I'm keeping the PGD site on top of Google results (except from my home computer I always visit PGD by first searcinh it on Google and then folowing the serch result link)

The best way for advertizing PGD is by making great games and showing all of those who say that you can't make good game with objective pascal that they are wrong.
Another good way is to make useful game development tutorials.
I have some of theese somewhere on my To-Do list but can't find them right now. WAAAAAAY to much stuff on my To-Do list
