Remove "View recent blog entries" from User page.

There might be better ways, but I did it using hook_user_view_alter in a custom module:

function your_module_user_view_alter(&$build, $account, $display) {
  unset($build['summary']['blog']['#markup']);
}

@robotjox that's the right approach, but the better way would have been:

function your_module_user_view_alter(&$build, $account, $display) {
  unset($build['summary']['blog']);
}

You want to remove the whole part of the render array, not just the #markup.
