Something is messing up this page on Safari, and (not having a Mac to test with) I can't figure out what on earth it could be.
The problem pre-dates the addition of the clustermap in the right margin (which will start functioning tomorrow, if all goes well). As far as I can tell, it also seems to be unrelated to the previous change, the addition of the Google page rank graphic in the right margin. I've seen a screenshoot and both of the outside columns are overlapping the center one, leaving a wide swath of blank stuff where the two outside columns should be.
I know that my HTML isn't completely standards compliant; some day I'll move to wordpress and do a better job. In the meanwhile, if anyone has a suggestion as to what might be the cause of this problem, I would be grateful for advice.
