The only logic I can put behind these social networking sites is when it comes to matters of distance.
For instance, I hate talking on the phone but I like to keep in touch with my friends back in North Carolina, so MySpace and Facebook allow me to do that, minus the absolutely insane long distance rates that a phone call would cost.
I could always IM them as well, but with MySpace and Facebook it's much easier to communicate as with conflicting schedules it's nearly impossible for me to be online at the same time as one of my friends. So I simply drop them a message on MySpace and/or Facebook and they reply whenever they can.
Other than this, I have no practical use for either of the two.
