As detailed in this portal post, XDA is currently reworking the Forum Moderator system.
Instead of having very specific moderators for each device, each manufacturer has now its assigned moderators.
Larger OEMs are split up into multiple groups (ie. International / CDMA / US / Canada / Tablets).
You can see the list of the assigned moderators on top of each forum, right above the forum rules.
There is also a global list of all moderators available here.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
