UK communications regulator Ofcom has published a report looking at the use of online communication services. The report reveals that WhatsApp is the most popular messaging app among UK adults, with 76% of respondents having used it in the past three months.

Wireless communications trade organisation CTIA-The Wireless Association has found that mobile data usage exceeded 1.1 trillion MB from July 2011 to June 2012, a 104% increase from the previous 12 months.

There are now 321.7 million mobile connections in the USA, the equivalent of 101% mobile penetration.

Juniper Research has forecast that the amount of mobile messaging traffic worldwide will reach 28.2 trillion messages per year by 2017, nearly double the 14.7 trillion messages expected to be sent this year.

It says most of this growth will come from instant messaging (IM), which will account for over a quarter of all mobile messages in five years’ time.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?
