I found out that I had the “first” Show HN post this morning when someone mentioned it on Slack. It's nice to think I might have some small footnote in a bit of Hacker News history.<p>Actually, about 5 months before I posted “Show and Tell HN”, I posted a link called “Show and Tell YC” (the link and domain is now owned by someone else, but the original post is at <a href="https://news.ycombinator.com/item?id=237544" rel="nofollow">https://news.ycombinator.com/item?id=237544</a>).<p>As lbrandy said, it was a play on the “Ask HN” or “Ask YC” posts going around at the time.
