Clarification

To clarify this once and for all:

http://www.2chan.net =  2chan
http://www.2ch.net =  2channel

famed japanese board = www.2ch.net or ni channeru or 2 channel or 2chan for short!
sprout from ni channeru = 双葉【ふたば】 = FUTABA = sprout,bud = www.2chan.net
all funny things like torturecat, AA charaters, schoolbus hijacker
cpmes from www.2ch.net

Although hiragana word "2ちゃん" actually means 2ch.net, alphabetical "2chan" is for 2chan.net.

2ちゃん means 2channel (2ch.net) to Japanese. The domain name of Futaba was based on that.
