Ask HN: Users who register but never use your web app
For my app, about 25% of the people who register never add an event to their timeline. While I might be able to improve this with some A/B testing, my feeling is that these folks are not the type who will ever be very engaged in the app regardless of the changes I make.
For context, according to a report by RJMetrics, 40% of Twitter users never send a single tweet [1].
What type of people make up this 25% and how hard should I go after them?
