Yes, the forum has gone very quiet but it's more likely because there are now other platforms for discussion and sharing.
Facebook has loads of Pages and Groups for him, two of which I set up.
There's more immediacy and ease of posting updates and pics which is why my activity level here has gone down somewhat....sorry, Kelvin!
Plus I'm writing my own blog on him, which is linked to the Facebook Page.
That said, I feel his music is unique and will live on no matter what.
He's likely to keep trying new avenues of entertainment whilst keeping his principal values and beliefs intact.
As for his stubborness in sticking with Mandarin, well, I think that's just him being proud of being Chinese, popularity be damned.
I'm proud of him for that.
