Nope, I'm saying if they care, they should read the instructions. I'm not saying I read all instructions everywhere, and I'm not saying every program/site provides them, but if it's something I care about (like who will see what items and information) then I look for the instructions and read them. I did it for Facebook and I do it for Google stuff.
You care enough about your privacy to have posted anonymously. If you ignored the "Post Anonymously" checkbox and I all of a sudden could see your username, you can't exactly get all pissed at Cmdr Taco for that. The lady who wrote the "fuck Google" post thought all her Reader shared items were going to all her followers. If she had her Reader set to private, they didn't go to her followers, except for those people in her followers who were already allowed to see her Reader shared items. But if she had her Reader shared items set to public, well, they're public. Anyone could already read them and they weren't private.
