I'm actually curious to see how they're reaching all those countries. SMS deliverability in India (where I'm from) is highly restricted for such uses. We have a DND (Do Not Disturb) directory that most people are registered on. This means that most people can't get marketing SMSs OR transactional messages of any kind. On top of that, you cannot receive messages after 9 PM. I had trouble implementing a Nexmo API once because of it. Now, I know you can override these rules in India with government approval. I'd totally use the Digits API if Twitter has this sorted out.

Honestly for most "real" projects, I just use the Bootstrap LESS source files for the normalizer, grid etc. and just compile my own UI components. I believe that for any app to be unique, it has to have its own visual style and when you use the whole of Bootstrap (or just about any other framework) you just can't differentiate yourself. Don't get me wrong, I love these frameworks. I just think they're good for quick and dirty prototypes / open source hacks.

I think the iPhone 5S Fingerprint Reader is revolutionary because it is invisible: http://t.co/AfQSFqAjBy.

The idea behind a single OS that works across devices is probably the single greatest thing that any company can do. Having said that, it's very difficult to set up an app framework that allows not only the OS maker but even developers to create a single application that works across devices. Kind of like media queries for native applications.
