Amen to everyone encouraging you to hibernate for a while. I believe the problem is not external forces but rather internal: you may have indeed lost your mojo.
I remember when I was six I complained about how one of the games we had for the TI sucked and should have some feature. My dad's buddy says to me, if you think you have a better idea then do it. So I over the next couple of months I wrote my first game in TI BASIC. It was slow but it was awesome, IMNSHO. In later years my mojo for the TI died off as I moved over to the Commodore 64, then the Amiga (the later which I never had the time to learn to program, to my lament.) Last year I had a bug bite me in the ass and I pulled out some of my old TI programs to start a rewriting and fixing, even converting from BASIC to ML.
My point is, if you really have the underlying want and you can take the time, sometimes you have to feed your own mojo. If everyone depended upon other people to be involved to encourage their own involvement, nothing would ever succeed. If you're a talented programmer and you believe in the spirit of Amiga, then stay with it, throw in, and be your own trailblazer. While there might not be others working at your level, at least you can support a community of people who are not at your level and appreciate what you do.
Besides, keeping these old machines running and back-porting modern features and capabilities is a bit of mental masturbation that a lot of us crave, and I suspect you'll have a difficult time keeping your hands off that stick.
