I think having no immediate tech knowledge makes you the perfect sounding board. She will already end up finding tech forums that will give her all of the opinions, except that of a mature mother with an outsider perspective. If she asks you a question, ask her about the subject in order to find a parallel in your own life. Her having to explain it to you will probably shape her understanding of it better than if somebody just told her what to think. There are way too many tech blogs out there with innumerable subjects and opinions. I couldn't even begin to tell you what they all are... You'd have to pick one specialty and start swimming through a deluge of information, blogs, podcasts, books. Also I'd say there are very few "right answers" in this overgrown industry, sort of like asking how you should build a house. What kind of house do you want?
