The Taipei MRT used to have a competition. If you could find three grammar mistakes or examples of Chinglish in their signage, they'd pay you NT$1500 (around US$50). I thought it would be easier to figure out who was responsible for the mistakes and then fire that person for incompetence. But who listens to me?
I took the above shot at the Chungshiao-Dunhua (忠孝-敦化) MRT Station yesterday. I think I know what's going on here. Someone with high-level position either signed off on the "It's so wonderful having Taipei Metro with us" slogan or coined it her/himself and the people working under her/him were too afraid or embarrassed to say it was Chinglish. You might be wondering how someone who doesn't speak English could be managing an advertising or PR company or department that makes English signs. Well, in Taiwan, there's a saying: "The dead wood floats to the top." Simply put, you get promoted for staying in a company for a long time, not because you're any good. Loyalty is valued over competence. In all my time in Taiwan, I can't remember seeing a single Taiwanese person fired for incompetence from a Taiwanese-run company. I have seen "foreigners" fired for sucking, but that's another topic. Taiwanese people get fired for the following: a.) Arguing with a superior b.) Making unwanted passes at a colleague c.) Being a good scapegoat when one is needed.
Getting back to the sign. I think what the ad or PR company or department is trying to express with the "it's so wonderful having Taipei Metro with us" is that the MRT has improved the quality of life in Taipei. I agree with that. If you think Taipei's streets are clogged with traffic, you should have seen them in the 1990s. A friend who lives out in Hsin Tien told me it used to take her up to two hours (on a bad day) to get to work. Now, thanks to the MRT, she can get there in 25 minutes. I remember walking to Chinese class when I lived in Yonghe (永和). It took around 45 minutes as I had to cross Zhong Cheng (中正) Bridge. The reason I walked was I knew how long it was going to take me. With the bus, it could be 20 minutes or it could be an hour and 20 minutes. The MRT allows us to time our commute. And it's cheap; riding to work costs me NT$20 (US$0.60).
BTW, there are some interesting stats for ridership at the Taipei Metro Web site. Ridership is up around 50 percent in the past five years: http://english.trtc.com.tw/ct.asp?xItem=1056489&ctNode=11767&mp=122032
