I'm guessing you don't have any products to advertise? If you did, you'd know that advertising is about picking the right audience. People who play games are not a worthwhile audience to advertise BlitzMax to. You might as well advertise cookery courses to people buying takeout pizza. You'd probably also be aware of the possibility of destroying sales of your own product while you failed to do anything for BlitzMax in the same breath. Bad idea all around.
I was talking about the specific case of building tools for bmax, not games. You just aim the advertizing to devs and problem solved.
The creator of the thread suggested advertizing on a site, why not that that himself?, im serious, if it benefits their product, i think they should do it, i would if i had a tool for blitzmax to sell.
