Honestly it never occurred to me, in the beginning, that anyone else would post there at all -- I didn't even bother to give a description of the territory that made sense without context.
But then it turned out that people posted things that sort of matched the vibe of stuff I generally care about, and that was the joy in it -- I had hoped that I could find people who would want to talk to me about stuff I think is interesting, by me bringing shiny bits of foil back to the nest that a handful of interested people might react to, and it has turned out way better than that, with people bringing their own bits of foil, for everyone to react to. Now I'm learning what the vibe is as much as laying it down.
It seems impossible that it can keep working like this, but I'm enjoying it while it does.
