For me, Facebook Messenger doesn't fit my needs. It's terrible on BB10 since they put 0 effort into making it for that platform. On Android, I agree, it's great. Likely the same for iOS. Whatsapp is the closest in terms of achieving true cross-platform usability. It's a great client on BB10, and on Android. That said, I rarely use it since most of my messaging is done via BBM or Facebook. The user engagement just seems to be higher on those platform. @gehr (Gary Klassen, inventor of BBM) really put it best when he said (paraphrasing) that in general, social networks fit various needs: Twitter - I want to talk to many people at large. LinkedIn - I want to talk to colleagues and business partners. Facebook - I want to talk to my extended friends and family network. BBM - I want to talk to people I really care about. And that's exactly how it's been for me for the last several years. My BBM contact list is limited to a few key people that I generally talk to or interact with in some capacity. I say and share things on there that I wouldn't anywhere else. In addition, the new BBM features they've added in BB10, like BBM Voice, BBM Video, and Screen Sharing are pretty freakin fantastic. I use those features daily, and I think it'll be great when it comes to the other platforms. An interesting use case that I've found for Screen Sharing is being able to have users demonstrate issues or bugs they're seeing in my apps. In any case, there's definitely a place for BBM here. I'll be encouraging a lot of my friends to grab it. Maybe even my parents, though I'm not sure I want to keep getting messages from them, LOL.
