I love how the BBC reports it as "UK and the world"

Whatsapp down, continent cut off

Oh man I've not read highscalability in years! Shame it only seems to be Stuff the Internet Says and sponsored posts these days. Used to love their articles.

Whatsapp feels like a glorified sms.

I have unlimited sms already.

I don't really see the point of Whatsapp beyond sms not being free. It's centralized, not entirely trusted or more trusted than sms.

So yes of course it's a technical feat, but sms is a bit more decentralized I think.

It's groupchat, better sms (with photos) and calls over internet, already integrated with phone numbers. Also its more reliable than sms.
