I'm beginning to doubt whether Matrix can actually succeed. It's a great idea, and there are great people involved, but there's just so many different problems/features that it's still lacking. And the progress is painstakingly slow. I really want them to succeed and I still try to get everyone on board and evangelize all my clients to join Matrix – but the truth is, I'm loosing hope.

Example: About a year ago, "Threads" went out of Beta and the feature is pretty much still unusable, because Notifications get stuck all the time. Even though there was a lot of progress to fix this – it's still not up to par with other Messengers.
