On March 12th, 1989, Sir Tim Berners-Lee put forth a proposal to make information sharing possible over computers, using nodes and links to create a web that would eventually stretch worldwide and become the modern internet. Now, 25 years to the day after he disseminated that proposal, Berners-Lee has called for the internet he invented to stay free and open. In a guest post on Googles official blog, Berners-Lee asked internet users to press for the development of a digital bill of rights that would advance a free and open web for everyone. Berners-Lee hails todays anniversary as a day to celebrate, but also warns that internet users should think and act ahead of key decisions on the governance and future of the Internet that he says are looming. In order to maintain unfettered access to an internet that is gradually becoming more restricted, Berners-Lee points to the Web at 25 campaign.
