I worked on Readability for its launch. I remember they had difficulty monetising it. But more importantly, the firm that built it, Arc90 (now Postlight), was acquired by SFX a few years ago who has no interest in that space. I'm surprised it has stayed up this long.

I suspect it coasted purely on momentum -- hosting fees or such.

The parser/converter has actually stood up amazingly well considering it's seen little or no updating.
