I noticed last night that Reversi wasn't showing up in my TiVos' menus, just the apps.tv IP address. Today I went to look at apps.tv in my browser, and sure enough, I saw this:
I've been expecting this for a while, but it's still a sad day for me. After taking down their own hosted apps, and purging others from the list, apps.tv was down to just two available apps at the time of shutdown: my own Reversi, and that Fire Dispatch thing. I figured our host was just waiting for them to give up before shutting down (not that he said anything about it). But I had no intention of turning off Reversi. Looks like I waited him out. (In fact, Reversi is still running as I type this, but without apps.tv, you can't get to it.)
On the one hand, I'd like to thank our host for providing a valuable service to the TiVo community for many years, with no recompense. On the other, I'd like to curse him out for being a bipolar flake and shutting down without notice.
