I have spent sime time today looking at other people's blogs. What a wealth of information there is available to us just from these! I have found an etch-a-sketch website which reminded me of my youth and a site offering to teach me mandarin.
I have also found the first Chinese 3D Virtual Tourism Site - Virtual Forbidden Palace, and a game to test my skill as a supermarket manager.
There is so much more out there so why not try searching google for topics of interest. But make sure you have some spare time before you start!
