Eighty years is within a single lifetime of today - but for many it will feel a long time ago.

25 years ago today, the Berlin Wall - a physical construction dividing a nation between two ideologies - came down. Not by bomb, not by fiat, but by hundreds of activists, emboldened by global public opinion, physically dismantling it brick-by-brick in the face of the same guards who only months before would have shot to kill.
What we see with data today is a similar situation to what we had in the era prior to Web 2.0, where there was a lot of content around, but socialisation over that content was not enabled.

As we celebrate 25 years of the World Wide Web, the Web for Everyone coalition wants to give thousands of people the power to learn new digital skills.
