Judging by the size of the rock on her finger, I don't think she runs her website for the money. Or for the need to recruit new fans, or impress old ones. She's 40, still undeniably appealing, but probably at a point in her life where she's doing what she's doing for herself and nobody else. I doubt she really cares about improving the resolution of the videos, which I agree are substandard in this regard.
As for the picture sets, I do disagree a bit there. Some of them are too stylized for my taste, and the g/g sets do nothing for me, but IMO she's had some really nice ones lately, too, including this week's "Boobarella". The set before this one was incredible as well.
At some point, Chloe is going to retire from modeling, and it will leave a great many of us in a very sad state, but nobody beats Father Time. Maybe it's happening now, maybe not. This is a woman who's had a 20 year run at the top of her industry. That's unprecedented, really. We should be thankful she's still diligently producing new work, for as long as that continues.
