I've never heard of Panic. I've never heard of Coda. I don't develop on a Mac and I'll likely never be in their target audience.
But reading this product announcement gave me a real feeling for the genuine care and quality that these people put into their work that I'm curious enough to figure out a way to try their product. As banal as another editor might seem to some, the care of craftsmanship that this post exudes is refreshing.
