Thanks! I surely hadn't notice that now we have a search box. Teaches me that It should have stroke me as a bit odd that it wasn't posted on HN already, and that rellying on HN identical URL "was posted already" mechanism is not really relliable.

I think a re-post isn't without merit though. There's plenty of people here (myself included) who might not have seen this article otherwise.

I never suggested it wasn't worth reposting - I just thought some people might like to know when it was posted, and see the previous set of comments.

Perhaps having an easy way to link up, or display, the comments from a previous post of the same link would be helpful. I myself find it really interesting to read old comments from a previous post.

It occurs to me that, since we now do have some sort of local search index built into HN itself, it should really be using that index as part of the "was posted already" mechanism.
