Mommy bloggers

I thought this was an interesting article discussing new disclosure rules for bloggers (not just traditional journalists anymore!), and how companies are actively seeking out strong, existing communities to promote their brands - specifically the mom blogger communities. Here's one quote from the article:

"Even as many campaigns have found that Twitter is a great word-of-mouth strategy, other avenues of social media like Facebook are becoming more important, Ms. Calhoun said. Also, video blogs, display ads and online surveys are all integral parts of promotions on the sites.

“Brands are really mixed on Twitter,” Ms. Calhoun said, partly because of the 140-character limit on posts. “Facebook is much safer for brands because it gives them a lot of control,” she said."

Do you think they're right? Is Twitter too limited to really shape and share your brand with these (or any other) communities? And are there other dangers that come with connecting yourself to mommy-blogging communities?
