https://www.dasdc.net/For those who don't know, Da SDC has existed since 2004.
Founded by a bunch of piano nerds who didn't like the restrictive nature they perceived on other forums, they decided to start a community where a thoroughly strong passion for piano(particularly virtuosity and speed) and intelligent debate thrived with the freedom to also have a laugh and indulge in crude humour, swearing, and general lack of restraint. A very laid back feel.
Over the years it has survived but recently it has seemed to experience a renaissance of interest and is a very welcoming good-humoured community.
If anyone has been there in the past or never had a look around - please feel free to join.
I 100% respect the formal nature of a forum like Pianostreet, but Da SDC is a kind of antidote to that. Informal, relaxed, and a thoroughly good laugh!
