So you still need a network to have value, only that you don't need a large network? You mentioned newsletter and RSS, which you don't have, so people have to visit your site to get the links. So compare to newsletter and RSS, your site has less value on the same scale of network, right?
When all the onlookers are gone, there will be only yourself on your site. Do you still want to post links there, when no one else is looking?
