TeamSpeak allows participation in coding/hackathon events in a more fun way where you can discuss about ways to solve a problem to ways to design the architecture.
It wasn’t that fun communicating in regular chat platforms where the discussions related to a problem set gets lost in midst of mere chats. Also, people make you get engaged in conversations and somewhat distracts you. Coders don’t want that to happen to your passion. This is why this dedicated chat platform is needed for passionate teams (even parted by distance) can communicate their thoughts and ideas to solve a bigger problem.
