Taiwan Panorama is a bilingual magazine that's great for learners of English and Chinese (it's actually published in Simplified, Traditional, English and Japanese). They have an excellent article on the state of the Taiwanese manhua/manga industry (summary - some great things are happening, but the market is dominated by translations from Japan). The article has some great recommendations for reading material and names to watch. It's especially fascinating for me because I'm working on getting my own comic book series started.
Comic books are a great source of intermediate level reading material. (Taiwan Panorama is as well, of course) Since reading this article, I've almost finished reading the first six issues of Chicken Cutlet Princess (鸡排公主), which was the big winner at the inaugural Golden Comic Awards. Perhaps I'll look into Hong Kong and Chinese mainland manhua as well.
