The content of the post is similar to the stump speech she has delivered in numerous recent appearances on the campaign trail; but its appearance on the popular site is significant as part of a larger trend by the campaign in putting Michelle Obama forward as a surrogate to niche forums that reach important voting blocs. She also recently reached out to a forum for Hispanic moms called Mamiverse.com, appearing in a video chat for that women's media outlet. These Internet forums might not be widely known, but are influential with certain groups and tend to generate strong loyalty in their target audience.

Editor-in-chief Stacy Morrison notes on the post that Obama is the first to respond to the site's attempts to reach out to both presidential campaigns.

"BlogHer has reached out to both candidates to ask for their perspectives, as well as those of their wives, on what’s at stake in the upcoming election," Morrison wrote in an editorial note. "Thanks to Ms. Obama for being the first and continuing the conversation she started four years ago with the BlogHer community."
