You're not a loser, it's just that BBM is probably a day late and a dollar short with their cross-platform offering. A few years ago, if RIM had released BBM for Android and iPhone, it probably would have blown up, as a lot of folks were still using BBs then, and even those that had switched still loved the platform and had friends using it. Now, however...that's not really case for most of us.
Unless I'm really missing something, there's not really anything that BBM offers that Hangouts doesn't (unless you have friends that are still using *actual* BlackBerries as their primary device), and Hangouts already comes installed on Android devices and everyone with a Google Account already has access. There's no awkward, "hey can you install this app so I can chat with you" that needs to happen, especially once everyone has the updated SMS-enable Hangouts app, because everyone will already have it. With Hangouts, you can just lookup your existing contacts by gmail address, and if they're available to send a message you're good to go...otherwise you send a standard SMS text. With BBM, as you mentioned, you have to get your friends/family to install the app, then register for an account to get a PIN.
When you add to that the fact that BBM only works on ONE device at a time, compared to Hangouts which works across all of your devices, just seems like a no-brainer to me.
If you can get your friends to use BBM, more power to you, but I have a feeling if you stick with Android you'll probably end up using Hangouts as well anyway.
