The scope of content at Facebook is growing enormously, and an attempt to do networking there, in a qualitative manner, easily disappears in the everyday flow of info about people's various activities.
So, what I need, is a site with a focus on one field of human activity: the world of vocal music. The Real Group launched a website for this purpose only and I'd like to invite all my friends in the vocal world to join this community.
Maybe, one day, Facebook will become unnecessary for me as well. And so we move on, and move on, and move on, and move on.
