By all means do post information about PGD on other gaming sites.
But don't be surprised if you manage to start a flame war about Objective Pascal not being fit for games. And until we have some nice game to show you will lose that flame war.
Wel we do have Projekt-W to show that you can make good games woth Objective Pascal. So you might atleast have som chances in winning the flame war.

I know I probably sound quite pesimistic about this but the reason for this is that in the past I lost a few flame wars which got started after me trying to advertize PGD site.
