#foss developers: “THIS WORLD NEEDS MOAR CHAT APPS!”
@Steinar @moiety @Gina Having more options is of course a wonderful thing in general, and a big reason we use FOSS stuff. But when the purpose of the app is to enable you to communicate with people, then the more people you need to talk to who use different apps, the more apps you have to juggle in order to talk to everyone you need to talk to. In short, it's like an XKCD 927 dilemma.
