Our research suggests that almost all low traffic apps should continue to run fine on the `free` dynos. If yours don't, send me an email: pvh at heroku
Running lots of experiments is always good (hobby or otherwise), and I'm very happy to see Heroku still embracing experimentation. But it hurts your experiment when you tell someone to visit a site and they click away after a few seconds of a blank page.
Is there any work going into speeding up the wakeup time?
