I've kinda lost interest in 2ch the past few years, and from my limited perspective it seems like its glory days are long since gone. Maybe this will change once I start learning Japanese.
For me, "textboards" in general and this place in particular, is/was defined rather by its contrast to chan culture: a slower pace, long collaborative threads and more mature discussions (ostensibly by the exact same people as on less pleasant sites).

But maybe that's just me!
