I know that it's not much of a problem around here, but some places ownership gets the "cheap" label slapped on them pretty regularly.  I just did a four-part series on my blog about that, and I would like a little feedback on the methodology and results.  (What I could have done better, what doesn't make sense, etc.)  Since I know there are plenty of statistically-minded people here, I thought I'd ask.  Thanks!
