To repeat: “at the expense of joy, time and skill”. Hits home that!

This is something I worry about for myself, as alluring as the convenience is. I've used it a couple of times to get over the "activation energy" but have rewritten for clarity/style/functionality/belligerence reasons

I think this has a good chance of claiming its space next to the Story of Mel in the next couple years.
Not because the two are similar in any way, but because of the place it might have in dev culture/folklore by then.
