by "show up as microformats," do you mean, you have eg u-in-reply-to or u-like-of or u-repost-of in your posts, and you want BF to handle those appropriately?
if so, maybe switch to sending webmentions for your posts? that will make it handle the microformats.
@snarfed.org fair enough, will send those instead. thanks for the help! :)
