I feel that I should build a site/app on rating churches. First in the U.S. and then the world. Thus far I haven't seen such a site.
This site should be simplistic and informative. Showing denomination affiliations, ranking, rating, etc. Preferably, each church is summarized in a one row record. Links to various forums/discussions may follow for each church.
This will also help me in analysis of churches. For example, when dealing with various church sizes, would expectation from different churches be different accordingly. Keller's Redeemer is a large church, so when pastoral care/Sunday fellowship is lacking, one may think it fine for it to be excusable as long as they are active in other areas, viz. HFNY & community groups. But if a church is small, then lack of Sunday fellowship is simply deplorable.
This kind of information should be simplified into the site.
