I don't feel motivated to work on it (this particular artifact) any more. I want to make something relevant to and appreciated by an audience, and programmer culture seems to be unwilling to do that in a deep way.

If I continue, it will be with a specific story in mind about who it's for and what message to convey. I have been attending The Strange Loop for a few years now and growing some ideas to write about.

It's worth noting that Slate was one major project in a long stream of development I started privately in the early 1990's and then brainstormed with some nerds on at the TUNES project until I made Slate its own thing (a kind of stepping stone towards the TUNES goals).
