Just a small suggestion...
I thought it would be interesting to see a graph of how the scoring for a question (and its answers) has changed over time.
I guess for most questions, the bulk of the scoring would be within the first day after it was asked, but many good questions continue getting votes over time.
I guess the real reason for this suggestion is just to feed my appetite for statistics; it's probably not that useful most of the time.
That said, I can see how it could show some interesting trends -- for example, a spike in the graph might indicate that an older question suddenly got some fresh attention; maybe because it got linked somewhere, or maybe because it gained a fresh relevance.
Anyway, just a suggestion. I'm sure you've got plenty of other exciting new features to be developing, but it seems to me that this wouldn't be too much of a project.
Thanks for listening. :-)
