Oh yes! Reposts are welcome after a year or so. This is in the FAQ: https://news.ycombinator.com/newsfaq.html.

We particularly want new cohorts of users to get acquainted with the classics :)

When users (or mods) link to previous threads, the intention is simply to share other troves of comments for curiosity gratification purposes.

Yes, why not. When I posted my comment, year wasn't in the title. I was very excited to see this, sent to my friend and he said to me that it's an old one. So I posted my comment to make people aware of that.

Yes, I remember the GPS post, but somehow missed this one the first go-round. I love how HN can resurface an old post deserving of a few re-posts.
