i'll give people one free pass on creating a new account and then submitting their own stuff. but after that, i expect participation and/or non-self-serving submissions. multiple submissions without contribution is where i start to criticize.
I agree with this - I think a lot of people lurk on HN (like me) and only join when they've got something worthwhile to say. It's when it's all take and no give that it becomes a problem.
The only question I have with this is that I don't see why you wouldn't just register. I think most people contribute to HN simply by voting things up or down. I don't have the actual figures but I strongly suspect those people rarely if ever post. I don't have a problem with that.
But those people are "giving" with their vote and the people who don't register are "taking" albeit taking something pg is clearly willing to give (bandwidth). So when all you have to do to give back to the community is create a password and click the mouse on a few arrows why wouldn't you.
