Heather B. Armstrong, whose "mommy blog" Dooce.com garners nearly 100,000 readers a day, stopped by the "Today" show Monday to discuss why she decided to blog about her recent separation from her husband after almost a decade of marriage.

"I thought I had to talk about it because I felt inauthentic not revealing what was going on," Armstrong said. "I've been so open about my life for almost 11 years. I write about the day to day goings-on of my life and this was pretty much consuming me. It was hard to sort of write about anything else without revealing it."

Armstrong, who ranked among Forbes' 30 "Most Influential Women In Media" in 2009, called the separation "the hardest thing [she's] ever been through," but credits her followers and fellow bloggers with helping her get through it. "We've rebuilt our village," she said. "These are the women who would've sat around the campfire with me and help me take care of my children." Armstrong has two daughters, Leta, 8 and Marlo, 2.
