Ask HN: What did your 'Show HN' project turn into?

This weekend I waded through a couple of old projects and I thought about all the stuff I built over the years. I posted a couple of "Show HN" projects a couple of years ago and it was funny reading those posts again.

Basically all of the projects went on 'auto-pilot' right away, meaning that I didn't touch them since I posted them. However, my latest 'Show-HN' turned into a real business and three years later we are a three people remote team and we are growing quite fast (the project is called mailparser.io).

I was wondering what your 'Show HN' turned into? Any stories you want to share?

Recently I launched my side project[0] via HN. However seem like not much interest on the project.

Merely 2-3 people sign up and no activity after sign up. I dont know what to do with it and now I am not motivated to improve it. :(

Just some small feedback but since it's for developers, you might want to add authentication via Github accounts.

I actually first found HN in my weblogs nine years ago, when this guy called "pg" posted a link to a post-mortem I wrote up of Twiddla's accidental launch:

I actually spent today working on a new document viewer for Twiddla. It has been relatively successful, with tons of happy users, but still isn't bringing in the same sort of revenue as my other bill-paying product.

Edit: Here's the "last week" link that somebody mentioned on that thread. That must have actually been the one I found in my logs (since I responded to it):

About 2 years ago, I posted my side project HelloBox (http://hellobox.co).

Back then, I started as a tool that lets you create your own HackerNews clone. I did this, because every now and then, I was seeing Show HN posts that went like "HackerNews for XYZ". So I thought, I'll create a tool that lets you build your own HN quickly!.

Two years later, I'm still going and it's now grown into a community tool. Still not at the level that I want, but slowly getting there and hopefully monetize it soon.
