Wired News the excellent online news source have always led the way with their style guide when it came to digital terminology. Was it 'email or 'e-mail'? They decided 'e-mail' and that was that.
For many years they always referred to the 'Internet'. I have always done the same and when people have tried to edit my capital Is down to i they have been pointed to Wired News. The Internet is a place for me and thus deserving of the capitalisation. But internet technologies are different and a capital is not needed.
The good times are over though, Wired News no longer capitalise the i in Internet. Perhaps this is only important to pedants, but for Wired News the Internet is now just another medium for communicating information, not a place. Well j-dom.org is one place where the Internet will remain lovingly capitalised.
