Add permission for taxonomy similar?

I noticed on our site logs that some users were getting an 'access denied' warning along the lines of: Message: taxonomy_similar/node/nid denied access.

I have our site setup for free tagging on blog posts, as well as having controlled vocabularies for section and topic. Using this module, when a authenticated user submits a blog with or without freetags, they are redirected to the url: /taxonomy_similar/node/nid. At which point Drupal prints a message something along the lines of:

Access denied
Your personal blog entry was created.
You are not authorized to access this page.

I traced the problem to the way hook_menu() is implemented in the taxonomy_similar.module, 'access' is set to user_access('administer nodes'). In my setup, I cannot allow all users who will be using free tags in their blogs to gain this permission, so after a quick review of the availible permissions I chose to change it to 'edit own blog' for now on our site.

Is there a better way? Perhaps the module could add its own permission, instead of using a low level permission like 'administer nodes'?
