I don't really understand the hatred for "wapanese" on this site. If you're posting on a bbs that's basically an excretion of 2ch, you have no business making fun of other people's "wapaneseness".
Really, I think >>2, >>3, and >>6 are being real jerks.
This thread, as a simple greeting, may be worth saging, but that's no reason to flame and insult the poster. It might be a troll, but it's not like he posted anything offensive, so why respond with unbridled hostility? It's not like there's anything else worth reading on this board.
