I only use this to keep up to date on STLFurs. There are far too many spam accounts and sex bots. It is rather annoying. That being said, I do enjoy some of it’s features.
Featurewise, by far the best messenger out there. It's mind-boggling how many features it has and how fast they're adding new ones. More than a messenger really. An entire social network with so many channels providing info you won't find anywhere else.
For me, Telegram is the better WhatsApp. It works in the cloud, so no matter where you log in, you always have all your conversations with you, no backup, simply chat.
