When I first heard about it, I signed up for it and set it up on all of my computers and devices. I also evangelized it pretty heavily and managed to get about 10 other people to use it. Unfortunately, I ran into some pretty major issues with the desktop clients. They seemed to be coded pretty poorly, eating up massive amounts of CPU and/or RAM, and sometimes even causing my computer to freeze. In practice, there also didn't seem to be much point to encrypting conversations if there was no password required to actually see them (if someone got a hold of my computer). And (at the time) there was no way to delete a message. Due to these issues, I ended up installing it. I'm curious if things have gotten any better since then?
