when a person comments on a photo or post that person should be subscribed to receive updates about the post its common sense it is what makes a social network "social"
its not a suggestion its a it needs to be done as we are running social networks and our competition aka facebook has this feature and users ask for it left and right
and you guys rarely accept the things we need and you want us to go off site to use another service when you obviously have the means here to take our votes you guys are great but making users jump through hoops to be heard is a little played out
