Yeah, my parents bought an iPad just to talk to me over Skype (I still need to take out time and get on Skype for that though). I do think parents will do anything to better stay in touch with their kids. If Path or any other service can solve that problem for them, it can be a winner in the long run.
Well put, Ryan! Path is about intimacy & great for family.
p/s: my dad actually also uses Twitter just to see what I'm up to :)
