Clicking Tracking: there is MeasureMap, PMetrics, BlogBeat, Crazy Egg, but Google Analytics is apparently the best. What other tools and services for tracking your visitors would you suggest? I am about to start a new web design blog, but I don't know which tool I should use. Which are better? Which would you use for blogs and which for "normal" web-sites?

A statistics / scientific convention question. I've noticed in scientific journals that often when a set of data is presented with values normalized to one of the sample groups, and the value for that sample group is arbitrarily set to 1, 10, 100 or whatever, to simplify interpretation, the variability/error data for that one sample group is left out. Is there a good statistical reason for that or is it just some random convention with no good reason? [more inside]

How many people in the United States make over $25 million a year in pre-tax income? How many over some other threshold? Google is failing me, and census.gov is resisting my navigational efforts.

I'm working on a data graphic with a linear scale horizontally but a logarithmic scale vertically. The y-axis (count scale) values range from 0 to 200, with the mode average in the lower third of that range. I'd like the graph to take up only a third of the size vertically that it currently does.
I can recognize a logarithmic plot when I see one, and I know what I want generally, but I don't have enough of a handle on the Math to actually calculate and plot such a scale myself... at least accurately.
I'd appreciate any help in understanding the Math. It's one thing to see a formula, and another to know how to use it. I'm also not 100% sure that this is the best way to handle such a graph, so alternate strategies or confirmation are welcome.

As I understand it, the US election is won by winning areas and then counting up how many wins each person got. Give or take. It's not all that important to the question.
Does anyone know if/when the actual voter figures will be released? I'd love to compare this system to a true winner-takes-all system...
