I've used two of the webapps, however, the problem is in the workflow. On login, I was asked to validate from two devices. This is novel in this type of apps (at least, the mainstream ones), and it took me a while to figure it out. Part of the confusion was also the fact that notifications about validations started to pile up, and I wasn't sure about I was doing. I still don't know how I got the validation key (or however it's called) in this workflow. Another novel concept is that, as far as I've understood, sessions are associated to keys, so, I suppose, if I lose a key, all the (encrypted) communications are gone. This would be acceptable, but the warning is very pushy; it's not clear to a new user if it's very strongly advised to enable encryption or not (will the other people trust me without?). Communicating with other people is also confusing - I had two channels open with another user, and didn't know if any of it was valid. Joining groups was confusing as well. I had a name (which was also strange; I still don't know if it's normal for the names to be "strange"), and again, couldn't figure out if I joined it or not (until I joined via other means). This may be all necessary for a safe design, but definitely, it's a huge barrier to entry for somebody who expects a Slack-like experience.
