Please don't try and box the user base of a web community. It's exclusive rather than inclusive. You have no idea who is reading these pages.

It is less so OP's tool, and more so the way they presented it.

I won't discourage them away from SWEs. Instead, I want to encourage them to sell to core engineers. I was a MechE for the longest time too. And this is a great Matlab alternative. In fact, I was exactly that MechE who was using HN to feel like a part of the tech community.

The top post is phrased as a sell. But, if I'd read it during my MechE days then it would've gone right over my head.
