It's not that hard to get an invite. Ask in an HN thread and there's a good chance somebody will hook you up, assuming they either know you, OR can tell from your HN comment/submission history that you're not some weirdo who is going to spam lobste.rs with crap.

That works for users who have seen this thread. How does a person who has not seen this thread knows that they have to ask in some random HN thread to get an invite? What about users who don't have an HN account?
