Kent Shaffer has a great list of the top 22 churches in America over at over at Church Relevance.  I love the way he’s developed the thinking.  He took churches from 7 different lists compiled from 2004 – 2007, aggregated the results, and then made a list based on their presence on more than one list.  Very interesting stuff.  You can take a look at his work right here.
