The site is constructed via other peoples intellectual content contributions that they have in good faith ceded to him. It's why I don't journal there as it is just as easy to create my own website for free and still retain control of my work. Imagine logging an extensive amount of journaling there only to find out down the road you now need to pay to access it. Those journals are basically a gift to the owner who could generate income from ads if he chose to but when you try to charge people for what was given freely it will create some bad mojo imo.
The idea of holding all those contributors work hostage to a user fee retroactively has been tried before, most recently by Photobucket. Wonder how that worked out for them? I know I switched to free flickr which I discovered works better and won't go back even though they eventually dropped the annual fee idea.
