If you're interested in development of Chromium, there is one, new, very good place to look for news. It's http://planet.chromium.org/ and it aggregates info about releases, new features, and more.
If that's too much high-traffic for you, take a look at http://neugierig.org/software/chromium/notes/ (which is included in the planet). You'll often find there interesting Linux-related notes there.
