That is because the taggers are not trained on the same data. You can't expect taggers trained on wikipedia data to do well in anything but other wikipedia articles. On the other hand, if one has access to Amazon review data, (with links to the product catalog), I am pretty sure a tagger that does well on Amazon data can be trained.

Take a look at the Lowlands project from Copenhagen University (http://lowlands.ku.dk http://lowlands.ku.dk), which deals specifically with cross domain adaptation. You are right that reasonable domains are required though.
