Excellent question. Middle ignores karma in the quantitative ranking. Far to the right gets lower karma users. Users who consistently get almost all 1s and/or negative points are separately filtered out since they generally don't make for interesting recommendations. Users who sometimes have negative comment scores but also make lots of 2+ comments are included (these users are rare but are arguably the most interesting).
