Testing GNU Taler at #Datenspuren was fun. And by fun I mean mostly unspectacular. It just worked. I scanned a QR code. I got some Kolle Mate.
I think some sort of GNU Taler integration into #Conversations_im would be pretty cool.
If you would like to integrate Taler into Conversations there are currently funding opportunities available¹ from @nlnet and both the Taler developer as well as myself are happy to help with scoping.
