How would I know? I sometimes submit a link and HN takes me right to the original submission. But sometimes it lets me post the link. What do people do to avoid resubmissions, besides following HN so closely that they vividly remember the first two(?) submissions?
Fair enough. I don't know what other people do. If the link is very fresh, I scan the site manually. If it's older, I search first using Google. I grant that this may be more effort than it's really worth.
Rereading it now, my post reads a lot more aggressively than I meant it. At the time, I thought I saw this post (or the reply I linked to) a few times recently, but obviously that's not your fault. Apologies if I came off dickish.
Not a problem, given that HN does not try very hard to block resubmissions (by design, since the FAQ explicitly says that it is allowed), it is up to us to point out when a resubmission occurs.
There's also a response (which has also been posted I think): http://blog.peepcode.com/tutorials/2010/what-pythonistas-thi...
