Seems like a really simple web app concept someone should pursue. I feel like being able to browse other people’s TILs and save them/search them would be a really valuable thing.
True. I think that's the way the world is moving towards. I also see the 5000+ custom alarm clock apps out there as essentially forks of "deployed apps" for just alarms. But that was already predated by the explosion of websites doing the same XYZ thing (calorie trackers, photo storing apps, etc...) specifically before the mobile era. I think we're just seeing the same with the open source world as we've seen occur in more mature worlds.
