Amazon.com has a similar program. I buy lots of books from them and they know what I brows and buy then e-mail me suggestions of what I might like. Obviously the only reason for them to do this is to make money, but the majority of the suggestions are good and I have bought many things that they have suggested. Pandora internet radio works much the same way....
Perhaps the church could use a similar application in the future with its website recommending talks and videos after a user searches or reads articles.
I don't know, perhaps this is way too much work for very very little benefit.
