This is a great post that looks like it's falling through the cracks. I suggest you repost it later (you may need to use a slightly different url). When a solid story hasn't yet had significant attention, a small number of reposts are ok.
Edit: Never mind—it didn't fall through the cracks after all, which is great.
It's a balancing act between not wanting lame reposts and not wanting to miss solid articles. Currently, things have trended a bit too far toward missing solid articles.
Usually I add something like: Please don't overdo it. Accounts that repost excessively eventually lose submission privileges. Deleting and reposting is particularly bad—that's an abuse of deletion.
We'll do that eventually, but I'm hesitant to change the guidelines very much just yet.
Also, I think it's a mistake to overspecify the rules. We want HN to be a spirit-of-the-law kind of place. A lot of these details can be derived pretty easily from the core values, like "intellectually substantive posts". Accounts that abuse reposting and deletion are almost always just promoting stuff, which is not the same as posting what one personally finds deeply interesting.
But I'm just thinking out loud here. Probably a bad idea. :)
