Think I got it this time! I used the data structure that scorpio17 used (I printed out the dump here also). Output:

And here is the code:

use strict;
use warnings;

my %data;

    my ($user, $site, $cat) = /"([^"]+)"/g;
    push @{ $data{$user}{site} }, $site;
    push @{ $data{$user}{type} }, $cat;
}

for my $user (sort keys %data) {
    my $site_ary = $data{$user}{site};
    my $type_ary = $data{$user}{type};
    print $user, "\n";
    for my $i (0 .. $#$site_ary) {
        printf "\tWebsite: %s, Category: %s\n", $site_ary->[$i], $type

    my $type_ary = $data{$user}{type};
    my (%site_cnt, %type_cnt);
    $site_cnt{$_}++ for @$site_ary;
    $type_cnt{$_}++ for @$type_ary;

sub by_count_desc {

}
