In his first entry, Berners-Lee remarked on how the Web took off as a publishing medium rather than one in which visitors not only read but also contributed information.
"WWW was soon full of lots of interesting stuff, but not a space for communal design, for discource through communal authorship," he wrote.
That has changed lately with the growing popularity of blogs, which are online diaries that often let visitors submit comments, and wikis, which are sites in which visitors can add, change and even delete what they see.
Their popularity "makes me feel I wasn't crazy to think people needed a creative space," wrote Berners-Lee, who added that he decided to start a blog to get a chance to play with blogging tools.
Berners-Lee first proposed the Web in 1989 while developing ways to control computers remotely at CERN, the Geneva-based European Organization for Nuclear Research.
He never got the project formally approved, but quietly tinkered with it anyway, making the first browser available at CERN by Christmas Day 1990.
