You know that we know that you know that you can link to others without asking for permission, right? If you want to promote your site fine whatever, but please don't pretend like that is not what you are doing.
I think that's pretty unreasonable, man. I've been asking permission to share because I've had run ins where people have preferred not to share, and sharing without asking has aggravated them. When that happens, you have to change your MO on these things and be courteous enough to ask.
This breaks the HN guidelines, which ask: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize."
