Twitter is now the fastest-growing social network in the world, with almost half a billion people signing up worldwide.
59% of Twitter account holders are now active on a monthly basis, up from 50% in the first half of 2012.
The number of account holders who use Twitter at least once a month grew 40% in the second half of 2012 to 288 million, according to the internet research company Global Web Index (GWI).
This figure means Twitter – valued at $9bn (£5.7bn) – is growing faster than both Facebook and Google+.
No doubt something will replace Twitter one day but whatever happens, I’m confident the skills necessary to use it now, that experience and a working understanding of the key principles will give us the grounding we need to keep up with vital developments and changes in the way we work as digital communications technology rapidly advances.
