If submitting things from CiteSeer became HN's version of submitting Wikipedia pages, that would be a major step up, IMHO.
I am bound to agree. On the other hand, Wikipedia often provides good starting points for further research. Especially since they insist on sources. (Though their preference for dead trees doesn't help.)
Note: HN's scribd integration doesn't work for redirects to PDFs. Might want to fix that?
