Alertbox Software engineer Jakob Nielsen's excellent monthly column about web issues. Contains many pages with links to research results about online use and usability. Time spent exploring this site is time well spent. Examples are:
Megastories From the site's "who we are" page:
Out There News is a news agency born on the Net. It pioneers a non-linear journalism in which people create their own experience of the news rather than passively receiving information.
A web zine aimed at writers and editors who work in online media. There's also a mailing list you can join
Razorfish.com Contains the above typography site as well as a lot of other cutting-edge stuff, including a story told in nonlinear form. I find it difficult to navigate through this site, but I'm not a 20-something New York-type way-cool person.
Gif animations A fairly clear explanation of animated graphics from the C-Net site
The Philadelphia Inquirer A sentimental favorite. An easy-to-navigate site with sections and story summaries linked to full text. I am getting a bit tired of the animated ads.
