<br>OK, still trying to get my brain around Blir's stuff here. Some questions: What are the gray squares? Is that where a person voted for a band, but ranked them low? Also, the dendrogram loses me as you move up the tree. I get that I correlate well with Brock and that Brock & I correlate more loosely with marie3 and Plagiar. I take it the numbers are the correlations between pairs. What do eht numbers higher up the tree mean. How about a list of how everyone correlates with the average? Your software could spit that out pretty easily I imagine.

Gray squares - right, low points, there should be a continuous spectrum of gradations but the software does't show it very well
Dendogram - when you move up the tree, you're related to someone else by however far up you have to go. For example on the first tree, you're 61% to Brock but 34% to Marie3 and only 4% to Horrorgirl. You just go up the tree, find the juntion then down again. I think the second tree is more representative though.
Vs Average - same is true as for above. Just start with yourself, then go up then down to get to the average. That junction will be your correlation to the average. From the 2nd tree, you're at 58% from the average. But again, the numbers aren't absolute but relative depending on the clustering routine you use.
