I am on the fence about notifications though. They can be very useful for the user. I am planning to add notifications, but probably all off by default, and the user decides very granularly what they want on. Does it seem the right approach? I would appreciate any opinion
"You will only see public entries from people that have both being included in your list and included you in their list. No stranges following you (or even knowing you have an account)."
"There will be no way to like entries, only conversations. Also, there will be no way to share content outside of the list of who posted. So no way to go viral and no instant rewards."
"All the design decisions above already point to a social network with less activity. Adding to that, you won't see any advertising on the site, so there is no incentive to keep you aimless wandering around here. Stay as long as you need to connect with your family, your close friends, and yourself. Then leave."
