Comment (by boonebgorges):

 Thanks, jeremyfelt. I think I see how 'edit_posts' could be too
 restrictive.

 How about 'read'? All Subscribers should have this cap. On non-MS, it'll
 be functionally redundant with the `is_user_logged_in()` check a few lines
 above. On MS, it should limit to members of the blog, which is what
 sboivert initially wanted. The benefits over the suggested solution are
 (a) no ugly `is_multisite()` check, and (b) no pulling up blog details
 inside of `is_user_member_of_blog()`.
