Like the above poster, I am also a recovering hikikomori.
I stumbled across this page after looking up the term "hikikomori" in Google to see what kind of pages I'd all find on the subject of the hikikomori phenomenon.
A few weeks ago, I signed up to a site called HikiCulture; I'm not sure if any of you are familiar with it or not, but besides the AnonIB hikikomori board and this place, it seems to be the only option for hikikomoris to go to for discussion - http://www.hikiculture.com.
Anyway, it looks like this place has been somewhat active recently; I will try to post often.
