JJSWiki - Closest thing I have to a personal home page, where I can put info I find interesting about random things, just... in very decentralized wiki form. Worked on intermittently from 2006 to present.
JJSBlog - Basically for the occasional thing I want to write that goes way beyond tweet length and doesn't have an obvious place on the wiki. Worked on intermittently from 2016 to present.

Found here - Old
Garaph - Database site for tracking (mostly Japanese) game sales data. Worked on mostly from 2008 to 2013. The one thing I do keep up to date is the official hardware/software shipment data, as that only has to be dealt with quarterly.
DohBell - Database site for keeping info on Hello! Project (and related) releases and the people who worked on them. Worked on mostly from 2013 to 2017.

Found here - Really Old
Anicro Desapro - When the GameCube Animal Crossing came out I made a program to help convert images to custom designs that could be used in-game. Still useful for the DS game. This is its simple page, basically untouched since 2007.
Unofficial Rick Sloane - When Hobgoblins 2 was announced I was surprised Rick Sloane didn't have a site, so I grabbed the domain without very big plans. Then I unexpectedly got an email from Rick himself and felt like I kind of had to do more with it. Not exactly theforce.net, but I guess you won't find TOO many other places with more info on Rick Sloane? Mostly a 2009 thing.
