I also started an earlier thread asking about the curious inactivity of alex au's blogsite.
But hey, he is reported to be present at SDP 30th Anniv dinner, so he is back in town from his central america trip .....
dunno anyone who knows him personally.....
Possible scenarios, asked to cease & desist by gahment or else.
OR
he is not well physically
OR
he is in China to explore biz since he is running his own business where he is logged out from the majority of sites including his own due to the firewall. He forgot to install VPN.
Perhaps someone could ask the editors of TOC as they do have his contact details.
