I just find it annoying how you never know if anyone has posted on a photo of yours unless you check it specifically. As well as when you comment on someone else's video or picture and you have totally forgotten about it before they have responded to it. Therefore I am suggesting something similar to facebook where it will send you a PM'ed response saying "so and so commented on you picture (contained link)". You would then be able to respond to these comments much quicker where i know in the past it has taken months if not even years for some people to respond to others. I think this would also draw more people into the picture section and get more user interaction affiliated with this change.
