I created a Telegram group chat for Flock 2015 and it turned out to be very popular. Around 70 people joined the chat which is half the attendance of the conference. It was also pretty useful, some found an adapter to borrow, some found a ride back to Boston etc.
When Flock was over, I was going to delete the group chat, but some people suggested that we could keep it as a general chat for Fedora users and I was like “why not”. So if you’re using Telegram and want to chat with other fellow Fedorians, join bit.ly/fedoratg.
