3 years ago I did a Show HN [1] for http://asoftmurmur.com - it got 3 points, 0 comments
2.5 years ago I posted it again with some more features [2], got 190 points and 80 comments, and some positive feedback. Was encouraged to keep up development.
Since then:
* > 5 million sessions
* A native Android version written in Java with > 100k installs
* Native iOS version in the works
* I now work full time as a software developer
It's a small, simple application - almost a toy - and there are now lots of similar services, but it has genuinely changed my life.
