 Why not make people pay using karma points for each submission to HN?
bdfh42: Seems like an unwelcoming system for new users when (I assume) what you want to tackle is the very small number of spam posts.A bad side effect could be that HN users might be reluctant to post interesting items that were only likely to appeal to a minority of their fellows. Technical items on web development rarely get more than three or four up-votes and yet many are likely to be of interest to web based start-ups - part of the core HN target group.Does not feel like a net win to me.
