1) I recognize that my one example is purely anecdotal, but this has happened to me, and I was submitter on both.

2) Either way, even if the performance of a submission is a function of the submitter rather than the URL, it contradicts what the GGP of this comment said, which is that it is a function of content.

re pt 1:

Do you think some URLs are more valuable (better domain/more descriptive/etc)? Or was it just luck?

1) Better submission title (it was a pointer to a project I created, so I got to choose the title) 2) better submission time.
