This is Hacker News. Maybe I'm too old school but this project feels exactly like something that would have been written up in the/one of the original "mainstream" hacker news sources, 2600 Magazine. It is the embodiment of the hacker/tinkerer spirit taking something that was made for one thing and building something entirely different on it.
I guess the biggest feedback to the OP is maybe if things were presented in more of a proof of concept demo with disclaimers type of way rather then "use this service" type of way it would be better received.
That said, while I don't plan on actually using it, I still think it was a neat idea and kudos for getting it working. Thank you for sharing!
