In my time here on this forum - a mere few months but daily - I would say tolerance and respect are THE key features. Generally I find Internet behaviour depressing. It's a credit to the community here that a netiquette has been established that allows people to freely express opinions and post songs without fear of flaming. Sometimes senior community members have to step in but even this is done graciously. If you are respectful towards others then the forum is as democratic as you could ask for.

As for genre preferences, demographics and the nature of BIAB both play a role. The focus is on real instruments and they are generally favoured by people of a certain age for certain styles. There's no conspiracy.

Personally I enjoy connecting with other artists and I've learned a lot that has helped me in the 'trade'.
