any band who hasn't moved onto facebook is stupid
Bands use both. FB b/c it's bigger but MySpace allows a band to play their music thru on the page and the ability to customize their MySpace page.
Social Networking is only getting larger. The ability to connect with family/friends across the country and world is invaluable. Being able to see new pics of my nephew, what's going on with my friends in England wasn't as easy or accessible prior.
Similar to linkedin, I wish it was around sooner. Being able to stay in touch, contact colleagues from prior employers and network can be very useful.
Sure it may not be necessary for those that you are in constant contact with but for everything else...
