For 15 years I've been trying to learn what good I might be able to do on the Internet. I've seen some fruits of my efforts to free myself from my prejudices, and to help cheer and refresh the down-cast. I've had a lot fun practicing fellowship across religious and other ideological divides, but I haven't seen or heard of that doing anyone else any good.

All these years I've dreamed, in vain, of finding collaborators in those initiatives. Now I see some possibilities that look more promising.
