On the dichotomy between open and closed messaging platforms, in the context of XMPP vs Signal. I've linked to Seirdy's post on mostly the same topic, but the former exercises the exact idea I had in mind while reading the latter.
On that note, Snikket seems promising. Anything to make already-open protocols more accessible to the layperson is great in my book, though by having such a goal I hope they can figure out their funding story well. I'll be keeping an eye out on this at a distance.
Sidenote: Interesting that here's one project that's going against the seeming trend of Matrix. :)
