Mary Ann Zoellner, Alicia Ybarbo, Karen Moline and Laurie Kilmartin are four women from all over the mumiverse: two long-time producers for hit US show, The Today Show (both married mums), one best-selling author and journalist (a single adoptive mum), and finally, a professional comedian and comedy writer who was a finalist on Last Comic Standing (and a single mum to her biological son - she thinks). Over 152,000 mums follow them on Twitter (@TodaysMoms) each day and Babble.com included them in 'The 50 Best Twitter Mums' for the last two years running.
