I think most had high hopes for this apartment at the beginning as there were lots of clean limbed attractive nubiles visiting. However Deborah and Ian then set up on their own which must have been a blow to Helena. However of late there seems to be an unwillingness to perform. This could be fatigue (Helena at least has somewhere to go each day). Or it could be they have just discovered CC or it could be that their peer group don't wish to be exposed by cam or CC or maybe the novelty is beginning to pall.
Entirely their choice of course but the fact is that the majority of VH sites are competing with each other and mediocrity is unlikely to attract enough viewing figures to make the venture profitable. The choice is theirs.
