Musings on Geeky Mom

I'm in agreement with the general opinion that "Geeky Mom"'s blog was harder to relate to than some other things that we've read, due to its content.  However, the references to WoW did grab my attention, because it reminded me of the video game obsessions of my brother and guy friends. It was odd to read about role playing online games and what to cook for dinner in the same blog, but I guess that reflects Geeky Mom's description of what a blog is..."The author's voice is more of the defining factor."

I'm just wondering what the motivation and intention was/is for her to start this blog and keep it up for almost 6 years? It seems largely a type of personal account, but is there some other reason ?
