Well now you've been and gone and messed up the system... I'm afraid my puny non-fuzzy logic script only picks out the first node from each person in the thread. This is a fault. I know! I'm sorry! Anybody who has the time / skill to do better than this - let me have it, sibling:

#!/usr/bin/perl -w

use strict;
use CGI qw(:standard :cgi-lib);
use LWP::Simple;

my $url = "http://perlmonks.org/index.pl?node_id=110166";
my $html = get $url or die "could not get $!";
my %names;

while ($html =~ s/=(\d*?)&lastnode_id=110166">[^<]*<\/A><BR> by <A HRE
+F="\/index\.pl\?node_id=\d*&lastnode_id=110166">(.*?)<\/A> on \w{3} \
+d{2}, \d{4} at \d{2}:\d{2}//s) {
    $names{$2} = $1 unless $names{$2};
}

update: I notice that demerphq has done this already... as has crazyinsomniac.§
