Seems like it was posted by the same person, so I guess they didn't get enough traction two weeks ago and felt the need to repost it.

I agree. From the FAQ:

> Are reposts ok?

> If a story has not had significant attention in the last year or so, a small number of reposts is ok. Otherwise we bury reposts as duplicates.

It's not clear what "significant attention" means, and how many are "a small number". The other post got only 18 upvotes and 7 comments, so I guess a repost is fine.
