Hi, My partner and I made an (open source) app for meeting new people at conferences and events like FOSDEM. If you're interested in meeting new people this weekend, please try it out. It's at https://goodchat.io, and we've spun up an instance specifically for FOSDEM. We're not aiming to replace IRC/Matrix/Telegram with it. It's specifically for searching for people with similar interests, or who you are otherwise interested in meeting, and then contacting those people. It's part search app, and part messaging app. We made it because we find it hard to meet new people at events where there are hundreds or thousands of people, and we wanted to help solve that problem for everyone. Cheers! Sky P.S. It's a Django app and the repo is at https://github.com/red-and-black/goodchat if you want to take a look.
