I actually just checked her blog out. She does have nice buns, but her blog unfortunately gets into my 'not particularly interesting category' - consisting of mainly 'look what I'm doing' lifestyle posts.
Not that many people can succeed doing that. Judging by her payouts she's also in the situation of having to churn out one post a day, possibly two if she has expectations of a 'good income' (which she clearly does).
Personally I categorise hers as something of a hellish life - young, locked into a precarious income blogging about herself - that could all go sour very quickly.
Blogging about those other 'interest' categories' has got much more substance.
I think that was only responding to your first paragraph.
