I think BB sometimes put in glamour models as cannon fodder. They usually pick the ones without personality, so that:

i) They get male viewers.
ii) When they're evicted, they show up in glam mags for week - free publicity.

This year seems a bit different. Obviously we haven't seen much from Karly or Sophie, but they don't just seem like empty shells! We'll see though.

I also think some of the quieter ones will have a hard time getting an initial fan base, people like Saffia, Marcus...
