BoMag came up with its annual ranking by asking the people it's declared Most Powerful in the past to say who is the Most Powerful now. In other words, it's a perfect reflection of how America works today; them's who gots get more.
Note to Boston Magazine's online staff: Could you use some of your power and remove "wiki" from the title of that page? Because otherwise, you're going to look kind of silly in the sorts of circles that actually know what a "wiki" is. Granted, we don't have a lot of power, but that's a nice Wikipedia entry you got there, be a shame if anything happened to it, know what we mean?
