@sun i'm really annoyed that matrix went down the feature creep path and pushed it so hard as the irc replacement it clearly isn't. it's pretty nice for messenger use, has working crypto (never had real issues with the keys not present issue) and finally file uploads work.
systemd is just about reinventing and breaking things because that's all lennart can do. there already was upstart and others which worked fine. same with pulseaudio. esd worked fine. gnome is systemd gui now.
