Having read Brin's Uplift books, I thought this was an interesting prequel. There, uplift has been proceeding for centuries, and although people are arguing/fighting about how it plays out, the good of the research process itself is pretty much taken as a given. It's interesting to go back and see it as a stop-and-start thing that could have been abandoned if not for a very special set of circumstances (and humanity would certainly have been sorry if so).
I did like the relative post-scarcity setting of this story, exploring the idea of bored people following hobbies, and then this guy realizing that he could have not just a hobby, but a Cause to pursue.
So yeah, I liked the ideas in this story. Didn't much care for the main character, but that's not necessary for every story -- especially not for a short story.
