I personally like forums. it has its charm that gets lost in major communicators like Discord. our own place on the Internet, you know what I mean?
however, I do agree that forum sites are just not that practical for normal communication. many people lose interest before they even register; And because you don't check in nearly as often, discussions often feel more like writing emails rather than actual dialogue.
on the flip-side of the coin, forum pages are far superior at creating specific topics. especially when you consider the nature of PB, people make their own games. we can't give users channels for every game they desire, that'd be way too clunky. if everyone were to advertise in one channel, many would pass unnoticed. you shouldn't expect everyone to... make a website or YouTube channel for their game or something, you know? and for those that wish to show off their work, forums work very well.
I think this is a good compromise (for now). official forums and community run DC server.
