It's a fact I also noticed, Lena.
It's not only "Victoria" who doesn't attrack that much attention, but somehow it's a phenomenon that happens to the Swedish as well as the Norwegian or Belgian Family.
All of this families and Crown Princesses get less attention then Mary or Letizia.
Mary and Letizia appeared in the Royal circles around the same time; they were spreading lots of glamour and offered quite good stories for the gossips mags (pregnancy rumors and so on).
People mostly discuss their fashion and style.
Victoria is the most professional Crown Princess, but she didn't have
the "Glamour" moments yet.
My prediction:
When Victoria gets engaged, marries Daniel and has her first kids, then she'll be as interesting for gossip mags and forum posters as other Princesses. This seems to be the way it works.
Sadly...
