I was just about to search for a shiur by a certain rabbi, when Google Autocompleted the following list:
It took me a moment to realise that what I was seeing was a fantastic measurement of their relative importance! Since Google is now a measurment of our lives, this list at the very least, shows what people are searching for. I was surprised that Herbert Samuel made the #1 spot, but the rest of the list was somewhat illuminating. My only surprise was Harav Motzepi, who really isn't known outside the Haredi circle.
I did the same experiment in English but it didn't seem to work - only Boteach came up as a rabbi.
