I'm OK with WP displaying date and author on my posts, but both of those are links. Author goes to a profile page I'm not choosing to fill out (the whole site is mine, I have an About page for that). And the date link goes to a "static" page on my site, for no reason I can discern!
I'm running a child theme of Twenty Ten. My blog postings page never gets to the single post, single column view (I've inquire here about that before, but no response)--so I am not entirely clear which template page is actually in use.
