Count momlogic among the most influential mamas on the Web. Nielsen released its Power Mom 50 list, a collection of leading voices in the mom blogosphere, and yours truly made the cut.

Nielsen, the company famous for its television rating system, rated mom sites based on site engagement, number of Twitter followers (@momlogic has more than 32,000), ratings, and other metrics. Who else made the cut? Babble.com, BabyCenter.com, CafeMom.com, Dooce.com, and Bluesuitmom.com, to name a few.

Moms are a powerful group (as if we didn't know that already). Women between the ages of 25 and 54 with at least one child make up 19.2% of the online population and wield more influence than ever before, according to Nielsen Online. So-called "established moms" (those of us over 40 with three or more kids at home) use the Internet as a major shopping tool. Younger newbie moms use the Internet as a vital social networking agent. It's where we meet other moms and get information about things like pediatricians, weaning, and toilet training.

So, how do you spend your time online?
