Hi everyone,
Was wandering around youtube, and came across this link (and lots of related ones by the same guy).
http://www.youtube.com/user/Glossika#p/ ... amIn3hH_LM
In one clip he introduces himself as Mike Campbell, and his nick on youtube is "Glossika". Furthermore, besides Taiwanese, he seems to do clips for Hakka, Mandarin, and a number of other varieties of Sinitic as well.
This makes me very strongly believe that he's the guy who once started the Glossika site on Sinitic Languages. On that site, there were lots of tables showing the 8 tones (2 x 4) of Chinese, as reflected in all the descendent languages. Furthermore, the surname Campbell stuck in my head, from the days when I used to consult the site. I was very impressed with it in the old days, but after a while, it seemed to have been bought over by some commercial language-teaching company, and then never got updated or properly maintained after that (which was a real pity).
In any case, he seems to have a very good accent too. To me, he seems to have consciously learnt tones, as one can notice that he sometimes makes mistakes and then corrects them (perhaps mentally very quickly applying tone-sandhi rules, and sometimes not getting the rule right, or reading tone marks, but executing them slightly incorrectly sometimes). Nevertheless, spectacularly good accent too, IMHO.
