Pulling information from database

Good day guys,
I wanted to add social networking information to my author.php file. So this is what I did:
I added this to my functions.php file:

[Large code excerpt removed by moderator. Per forum rules, please use the pastebin for all large code excerpts. It works better anyway.]

The end result is this:
http://sharecommons.com/author/pangel/
http://sharecommons.com/author/shamrock/
http://sharecommons.com/author/jackdan/

Question: What should I do so that pangel’s social networking appears only on her profile and same with other authors. Right now, everyone’s social networking links are showing on everyone’s profile.

I believe, I need to change this particular code:

<?php
		$authors = $wpdb->get_results('SELECT DISTINCT post_author FROM '.$wpdb->posts);
		if($authors):
		foreach($authors as $author):
?>

What should I change this code to so that social networking links don’t mix-up with each other. Please help.

Thank you for any help you can provide.

Regards.
