Here is a website that indexes blogs by Fortune 500 companies. The index can be updated by individuals, so double check that any particular blog is actually operated by the referenced company. In any event, company blogs can provide information that is helpful and fascinating and maybe embarassing in litigation. For example, if you are suing a company that has a blog, the blog entries and/or the comments may provide you with very helpful information. In the same way, if you are representing a company that has a blog, you may want to check it out so that you will not be surprised.
I skimmed through the blogs, primarily looking for ideas for my own blog.
I checked the McDonald’s blog because I am interested in transfats and other food matters and wanted to know if the company had anything to say on those issues in its blog. McDonald’s has a corporate social responsibility blog that permits readers to get "personal perspectives on the issues, meet the people behind the programs, and hear open assessments of the challenges we face.� I found the blog to be self-serving and vague. For example, it emphasizes that social responsibility issues are complex and cannot be defined as black and white. While that is true, the complexity of the issues should not be used as an excuse for doing nothing. I am sure the people at McDonalds are well-intentioned. Even though I may disagree with the approach, a blog on social responsibility -- especially with respect to a large fast food provider -- will certainly generate discussion and help clarify some issues.

In the “about� section, the company notes that its blogging is limited by banking regulations. Specifically, for banks,

there are regulations that prevent us from obtaining your personal information—hence the restrictions in our blog comments that prevent you from submitting your full name. We're allowed to capture your email address for followup, but only after we confirm you're 13 or older. We can't capture your blog's URL in our comments due to concerns about phishing. And last, we can't receive an email from you unless we first confirm you're 13 or older. We know these regulations are there for good reason, to protect consumers from fraud, and to protect your privacy. So please bear with us.

Check out the index to company blogs, especially when you are litigating against the company. Even if you do not find anything that helps your lawsuit, you will surely find something interesting.
