I've really been enjoying the blog coverage of the WGA strike. There are quite a few writers that are blogging about the experience and doing a fantastic job at it. One I have been enjoying is Plaintive Wail.
He also posted a video from Friday's line at Fox that features Zach De La Rocha rapping (there are too many people with signs to be able to see Zach, but you can hear him).
Here are some more sites that I am enjoying:
LateShowWritersOnStrike (and cleverly enough, it really is them).
Nikki Finke's site.
