Today's moms are always on. In fact, a recent study, "The New Micro-Leisure," found that Millennials in particular (Millennial moms included) rarely go 15 minutes without checking their phones. As I talk with moms, I often ask them what brands they follow on social media, and which companies inspire them the most online.

Earlier this year, Heather Armstrong, the so-called Queen of the Mommy Bloggers, announced that she had begun to shift her attention away from blogging. The challenges of the job - from aggressive publishing schedules to demanding advertising contracts to concerns about her family's safety - were resulting in what she called "a dangerous level of exhaustion and dissatisfaction."

As they have done with most aspects of life, Millennial Moms have put their own mark on the workplace and how they view employment. Millennials now compose 34% of the workforce according to the Department of Labor Statistics, outnumbering Boomers and Gen Xers who represent 32% combined. By 2020, they will represent 46% of all U.S. workers. They are entrepreneurial in spirit, mostly because they seek employment on their own terms.

Millennial Moms have been the focus of our attention for a while now, but smart marketers are already looking ahead to a generation of moms just appearing on the horizon: Gen Z.

It seems influencer marketing is on the tip of everyone's tongue these days. So it's particularly interesting to hear that one of the findings of the 2015 Women's Blogging And Business Report put out by iBlog Magazine showed blogging was on a decline. The report found that 55% of bloggers work on their blog 5-20 hours weekly, and that only 22% claimed to work over 30-35 hours or more.
