As Alerte says, some girls may not want to interact. I would only ever want the girls to interact if they wished.
I can understand why some girls don't interact when you see things that are said in the reviews. They may be afraid of criticism or ***** and that is understandable.
However, it does surprise me slightly that there are none who interact at all, even if they use special forum accounts.
Frankly, from a markting point of view, it makes more sense for them to interact, even if it means promoting their own cards, especially new ones.
Of course, that mean I wouldn't expect to see anything from girls who aren't releaseing anything currently.
But anyway, all this is irrelevant if none of the girls are willing or interested.
