I found the content of The Digital Mom Handbook to be mostly an autobiographical pep talk. The appendixes (arguably the best part of the book) are extensive, listing a lot of blogs and other websites that might be useful. But aside from that, the book really doesn't offer much helpful information.
The book is not without merits, but I found that I couldn't really relate to the authors; and though it does sound like they worked hard to develop profitable online presences, there was probably a fair amount of luck involved. Also, they had the benefit of backgrounds and experiences that most pro-blogger-wannabes don't have. For example, Audrey McClelland, who developed her brand around fashion, previously worked for Donna Karan. And she had previously interned for an ABC affiliate, which gave her a tremendous head start in being able to produce quality videos for her blog (yet she offers few tips in this area). Colleen Padilla has an "Ivy League MBA" and began her online career by selling expensive designer pocketbooks on eBay (very risky and requiring a lot of operating capital). Padilla had a tech husband who helped her get set up, and McClelland "simply hired help" (something that is reflected in the fact that their book has almost no technical details). Again, both authors *earned* their success, but without their finances and other advantages, they may never have succeeded, despite their hard work.
If you need motivation to get started creating your online presence, you might like this book (maybe a lot). But if you need help with the technical and practical aspects, you would probably be better off with another book, such as
Blogging All-in-One For Dummies or
Blogging For Dummies.
