Not just artists.
If you post your personal pics online and if for some reason you can't be found, the corporatocracy can claim your photo and make money from your image, and there won't be much you can do about it after the fact.
I'm concerned about the social ramifications of an artless world. If this passes, I refuse to give money to anyone. I'd rather keep my work to myself, except for those pieces that will naturally become an act of protest.
Please, if you haven't already, click on the link in the first post and write your representatives. This bill was already hotlined through the senate (last Friday night...you know...instead of working on the $700 billion bailout!)
