I personally still love the game and concept and have no desire to see the game end. On a practical note I realize things change and if people want to stop then that's what's going to happen. Comparatively it seems I have little in means of a life as I've tried to make it a point to look in on the game on a daily basis, but nothing is progressing.
One idea I considered is what if the players had a bigger hand in the plotting process? They don't have to know every detail, but it couldn't hurt for them to feel like they have a greater hand in how the plot progresses. Also, what if we restarted chat sessions. If people can't play all the time, maybe chatting could at least allow people to spitball ideas, maybe casually in rp in chat, just get the old juices flowing again.
