I'm still occasionally (passively) dropping links to this site (in forum signatures in a few places), so I figured I'd write a short post to explain why there haven't been any posts.
Microsoft officially terminated XBLIG last year, and it is in the process of grinding to a halt. Though disappointing to me, I think it was a reasonable move. They want to distance themselves from further Xbox360 support, push more people to Xbone, and improve their general implied guarantee of game quality with the much-more-stringent ID@XBOX program.
That said, I've heard MS have recently decided to freely distribute the means to put an off-the-shelf consumer Xbone into development mode for Windows Universal Apps, so if I ever take the Win10 plunge (unlikely, but maybe I'll get bored some day...I did, after all, sign up for a chance at a HoloLens dev kit), perhaps I'll revisit the Xbox development effort.
At any rate, until then, my efforts are devoted elsewhere. At the moment (Apr 2016), a DIY quadcopter project that I may post about over on my other blog (read: my other equally-rarely-updated blog).
