On January 5th, Circus Ponies, the makers of the NoteBook app for OS X announced that it's closing its doors. Very limited techical support may or may not be available.
The Circus Ponies website now says:
After 13 years in business, Circus Ponies has gone to that great Alphabet company in the sky. It was a good run, but we are done (as in no longer in business).
If you need a copy of NoteBook 4.0 (3.x and earlier don’t run on OS X El Capitan) or need technical support, you can try sending an e-mail to email@example.com. There's a chance someone will respond but no guarantees.
The company was known for its NoteBook app, a virtual electronic notebook allowed the user to take notes and organize information on a Mac.
We've asked founder Jayson Adams for more details, and if we learn more, this report will be updated.
[UPDATE: January 6. Jayson contacted me and wrote: "The people reporting that we were purchased by Google have lost their minds a little. I understand why someone might connect the dots that way, but neither www.circusponies.com nor www.circusponies.xyz says anything about Alphabet owning us. I mostly just thought it would be funny for Circus Ponies to be the “C” in Alphabet. I am flattered that people would think that Circus Ponies was on par with Google and all the other multibillion sub-corporations Alphabet owns."]
