A double edged sword - creating methods of 'too easy' submission will most definitely lead (in my opinion) to a downgrading of quality. I've been on HN, not on this username, since the first link from Reddit when it was a few months old it's grown relatively slowly but has attracted a core of decent members who submit. However on the other hand it's necessary to improve quantity of submissions. I'm trying to stop going to Reddit & Digg altogether but it's hard when the update traffic is light years ahead.

You have to make a decision at some point - keep this place on the 'down low' with fewer submissions or break it up a bit.
