Congratulations to Dalton and co for trying something hard and worthwhile, and wrapping it up responsibly when it didn't pan out.
Not sure what more you can do when the business isn't going well. 2+ years of maintenance, open sourcing, 2 months notice, data export, no additional billings.
Respect to Dalton and the team.
I hope we find a way to pay for this stuff more than I hope getting it free becomes standard.
The primary memory which I have of that era are people not wanting to pay for something which wasn't clearly useful, shrugging, and going back to Twitter where most other people were. By the time app.net finally launched the free tier the self-inflicted damage was already fatal.
