Well. We learn from our mistakes. We have been always trying to develop tools, that make web apps the way WE think they should work. Not as our potentials clients see 'em work. True, we have been always talking to clients on features, but we never actually knew how the market at large is doing with the progressive web. What's the current reality?!
It took us about 9 months to deep parse about 300 million top-level domains and billions of connected web pages to learn the current state of Progressive Apps in the World Wide Web.
Done! We cataloged lots of interesting things to guide the development of our own tools.
We also gladly share the high level data with the wider market. This data was already used on several online and offline conferences related to Progressive Web.
