The cost of having a blogger register every post seems like an implementation detail. There's no reason Wordpress couldn't auto-register every post the say way it auto-publishes posts via RSS. Alternatively, you could simply register the blog as a whole with the copyright registrar and the Library of Congress would be responsible for periodically re-indexing your site. As a final compromise, we could grant the creator something like a 10-year window to register. Any copies made prior to registration (and maybe within a 30 day buffer after registration) would still be allowed, but any copies made after registration would be limited by copyright. That would allow for easy initial consumption and re-use (including archival and scraping) but permit the original creator to have some say over large-scale commercialization of his or her "greatest hits". As a philosophical point, I think it should be on the creator to register every creation (at least if said creator wants copyright protection on it). You are claiming a property right over an amorphous thing you do not physically possess. The least you could do is to be provider clear notice to the public of what exactly it is you are claiming rights over. In that sense, copyright is less like personal property and more like real estate, where owners are expected to register their deeds to enjoy full legal protection of their property rights. Also, as a practical matter, we're also more likely to see registration requirements passed than a reduction of copyright to 5 or 10 years (historically, it's been about 14-28 years in the U.S.).
