The largest polish Q&A site, helping millions of users get answers to the most unusual questions imaginable they come up with.
Zapytaj.onet.pl is a UGC-based project, where the community asks questions, provides answers create clubs and tutorials, engage in knowledge/fact-checking battles.
Every day up to 10 000 new questions and ten times as many new answers are published, making it the most heavily used Q&A site in the polish web. But it's not only the sheer amount of content that makes Zapytaj.onet.pl the leader - but also technology used in the project.
Mobile version of the site has been build from ground up as a PWA (Progressive Web App), combining native-like experience (speed, features - i.e. offline mode, push messaging) while avoiding traditional mobile apps' drawbacks (heavy download, unwillingness to install new apps, need to update).
