Like everyone else here, I didn't want to see Stringify decommisioned, but realize this decision is out of your control. While I'm saddened to see the service disappear, I want to convey my appreciation and thanks to you for all you've done, especially over the last year (when you've worked almost single-handedly).
My best wishes for whatever you decide to do in the future!
Edit - I know Joey left sometime last year, and Dave Evans moved on to other projects about 2 years ago. If you can - forward my appreciation to them as well ...
