I'm getting really tired of all these proprietary instant messaging solutions. It won't be long before people will realize they will at some point have to pay for usage of WhatsApp. When that happens, something else will gain traction, restarting the cycle again once more.

I hope Google just acquires WhatsApp already and opens up the platform. It's been years now, and about bloody time for something to appear that's the standard, open, cross-platform and free way of sending messages over the internet.
