[support] Strategy Help Needed for Link Rolls

Drupal Supportians,

My preferred method for links pages is to keep my links on Del.icio.us and use their awesome link rolling wizard: http://del.icio.us/help/linkrolls.

However, it just occurred to me that re: Technorati, Google, etc, that these links being dynamically generated from Del.icio.us may not be registering as links on our site that increase "authority" in the case of Technorati or help with SEO for those sites re: Google.

1. Can anyone confirm that indeed, links generated dynamically via the del.icio.us link wizard don't generate "real" links on the site in terms of Technorati and Google?

2. How do you do link rolls on your site?
