@Cycloptichorn,
Quote:Your test not-withstanding.....
Numbers don't lie. Try the Boolean "AND" linking "politics" AND "marriage" or any of the other irrelevancies you list, that also the forum classification lists. The correlation isn't with number of threads it's with actual enumeration.
Another test you can try after you get into the "politics" category is looking how many sub-categories mention "religion", "israel" and other terms that never come up in statistical correlations. If there's some religious fanatic peddling his agenda here then that should be disclosed to A2K members imho, that's the only point I'm making, because obviously it can't be a tag cloud coming up with those results.
