This post seems too dramatic - it looks like she is simply admitting to learning from what her readers read. If you build an audience writing a certain way, it's likely that your readers also have something of value to contribute and inspecting what they read and in turn offering it to other readers on your website is clever, if anything.
Also, it's just not nice to publish personal email communication. Just bring it up with her over a coffee or something.
I don't think it's particularly dramatic -- many of us find blogs in general to have more moral ambiguity/flexibility, and less of a understanding of the power of persuasion. This is an absolutely rampant issue (did Marco or Atwood recommend that hard drive or coffee carafe because it's the best...or because it's one that they could post an affiliate link to? What inspired that post?)
