Do you have an organization that does business in Taiwan? If you do, then a .org.tw domain is a no-brainer. After all, it's got the notoriety of .org combined with the locality of .tw, so you've got a nice package right there. But what if your non-profit isn't in Taiwan? Well, if you want to get some attention in the region, then a .org.tw domain fits in nicely. Then you can show the people of Taiwan that you care about them and their needs, too.
