How to allow a block on a page to load another block on same page in Drupal 7? This is what I am looking for: On a page that has a block, I want the ability of a link within that block to load another block on the same page. (Specific case: a static page has a Views block containing a grid of team members with a 'see more' link under their picture. I want that link to load the user profile as a block, but on the same page - presumably this should use ajax).

Any help on how to do this would be supremely appreciated. Thanks.

Can't post images on Drupal.stackexchange yet but here are two screenshots to illustrate what I am looking to do: http://goo.gl/WBgcR
As i understood from your problem, i think you can benefit from this lesson
Ajax node reader in drupal
http://www.youtube.com/watch?v=zyLmQtiSXgI

and there is a module called Ajax Blocks, can benefit u if u wnt to creat ur own module.

and as alternative solutions u can use
 http://drupal.org/project/colorbox_node
so the user profile loads in colorbox modal dialog
