[Arnavion]

The original intent for all the boards was for anime fans to talk about something within their group (ie with other anime fans) that wasn't /a/nime itself. There's a screencap from an old /g/ thread on the same topic (someone complaining about all the weebs shitting up their board; meanwhile the board is literally named that because of "gijitsu"). But over time many of the board cultures shifted to the extent that they have / want very little association with anime.
