I have already made a couple of posts at the Taiwanderful blog. One introduces some of the events on the event calendar. The other highlights some of the content of David's Guide to Taiwan. I will continue to use the Taiwanderful blog for these two purposes. There is also a feature of Taiwanderful that allows blog posts to be incorporated into the guides as book pages. If I create a new book page that I think is also suitable as a blog post then I will post it on the Taiwanderful blog.
As an example of how the two sites can work together, after visiting the exhibition of Tasmanian art on Sunday I wrote about it here. I also added a new page about the National Museum of History at Taiwanderful. I will also add links to related content from Taiwanderful here just like I might add links to my photo gallery or flickr.
Remember that anyone can register at Taiwanderful and start their own blog, post events on the calendar, add weblinks or create their own guide.
