Hi, it's John. Twitter overhauled the API and broke this account. I don't know how to fix it—frankly, I hardly knew what I was doing when I built it 7 years ago. Can't even log into the server that hosts the app.
If I get some extended free time this summer I might try to rebuild it. A big if though. Please, if you want to take a stab, I'm more than happy to hand over the keys, the existing code, all of it. Hit me up at @riccoja
