Not bad!
11925 in OVT and 1,370,000 hits on google for "Chinese Character"
.Net might not be the best extension for it, but still have lots of use!
(online application for learning chinese characters for example,
or some kind of dictionary)
I'd say low to mid XX, probably closer to mid :imho:
Try to find someone who are creating web sites related to chinese language,
or develop it yourself!
