This is silly on multiple economic levels.
I’m not charging money for my content. So, investing in a hypothetical DRM technology would need to be less expensive than the lazy and apathetic strategy of simply not posting. For the sake of a few more paragraphs, I’m going to progress with the assumption the investment is worthwhile. Why would it not work?
My journal entries are boring. These unwritten entries, in particular, are only appealing to the very demographic I’m attempting to restrict. Thus, the legitimate consumers of the content (people I don’t care about reading it) and the people who actively want the content (people I don’t want reading it) are left in a market situation nicely handled through the application of capitalism. That pesky invisible hand will only fight against me!
With that, the world of technology has been left and only a social solution could resolve the situation. Is there an already existing model where in a person who wants something willfully abstains? As appealing as trusting a communal construct, they exist as a imperfect system of percentages and statistics. There will always be terrorists.
And I’m left with looking at two buttons on my desktop. First one is the drop-down switching a post from Public to Private. T’other is Logjam‘s close button. I could always post anonymously, but where is the fun in that?
