...now that I've had a chance to participate in the voting for some time, I find that I'm still not using any negative votes on most days.

I have discovered that I have time to race in here, read for about 20 minutes and grant an up vote to any nodes that I feel contribute to the information worth of the site.

I find that I'm not usually here for long enough to be stingy with my votes. I have about enough time to search for information that's interesting or useful to me, and read a few things serendipitously, and then I have to go.

I think that a useful extension to the voting system would be to allow a person to cast multiple votes for a node. We are given a finite number of votes each day, but it would be nice to spend them en masse for a really good (or really bad) node. Perhaps the scheme would still have to contain a built-in natural limit (such as a maximum of three or five votes for a given node).
