Since Tepan doesn't see my comments, I won't go into details about what is wrong with his dialect, even from a conservative point of view. I just not the usual problems, not the weird ones: he uses 'pi' with only one following word, especially 'pi ni:' for just 'ni:', although he also says that the 'pi' should disappear in that place. He tells the usual tale about 'pi' joining nouns and, as usual, follows it with examples using adjectives (called "nouns" for the occasion). And so on. He is very judgemental about usage, disallowing many common practices (called slang or worse). Interesting to read, but not to heed.
