As someone who uses what's app loads and have never done Facebook it looks like we will have our spaces invaded whether we like it or not. This bloke Zuckerberg is like Nool on steroids.
"Once complete, the merger would mean that a Facebook user could communicate directly with someone who only has a WhatsApp account. This is currently impossible as the applications have no common core."
Has it ever occoured to Zuckerberg that just because I know someone it doesn't mean I want them to contact me?
