I actually have owned Poker.tw in the past (but unfortunately was not the one to sell it for 30K). Traffic is virtually zero. It's currently parked at Sedo and they say it had 7 hits in the last month, which may have been a few people looking it up as they came across this thread.
So you can imagine, in a country where gambling is so popular, if even Poker.tw gets no traffic then there is little hope for other generics. Maybe there is a reason they are still available
