Getting rid of personal blogs
You can alter the title of the link using hook_node_view_alter in a custom module.

For example 

function MY_MODULE_node_view_alter(&amp;$build) {
  // dpm($build['links']['node']['#links']);
  $build['links']['node']['#links']['personal_blog']['title'] = t('view company blog');
}


You will have to use some logic to only apply the link to a certain user etc.

I'm not sure about the actual link concerned so if you have devel installed, uncomment the dpm() part and inspect the array to find the correct link.
