The Web can be a bit of a lonely place if you don't connect. And the Classical Music community suffers more from this than other groups, people from all different backgrounds, showing a relatively conservative outlook, however liberal we may be in person, and not then quickest adopters of tech in the world. If you're into cars, or fashion, or even guns, I'm sure you won't have any problems finding mates to share your interest. But until only quite recently, the Classical Fan has been struggling to connect.
One of the oldest, and still thriving, communities is the Piano Forums at Piano World. Here's where piano makers, piano tuners, piano players, and just plain music lovers can go off into their separate rooms and start and contribute to threads of discussion. It's a well regulated, and dare I say it, a well tempered place. Drop in for a chat here
