Doing some marketing kind of stuff on bitcointalk every once in a while definitely does make sense but there are much (much much) more important channels in order to really increase volume.
Some people just seem to overestimate the importance of bitcointalk when it comes to player acquisition - I used to do, too.

I understand your point of view, but I disagree with you on some points. When it comes to cryptocurrencies, Bitcointalk stands on top when compared to Reddit, YouTube, Twitter etc in terms of gambling discussion etc in my opinion.
This is what I observed over the years. Stake, Roobet etc are some of the best examples to prove how vital Bitcointalk was in making them successful.
Correct bitcointalk is at the top if we talk about numbers of crypto users but its also good to market outside since there are also crypto users who doesn't use bitcointalk at all, many of them stay on the platform mentioned by efialtis so if they do multiple campaigns on various platform well possibly they can hit the greater audience and bring them here to play.
