Sadly have not gotten this to work. Error is as follows, but I can't find a reason for it to trigger.

Unable to load query for transaction type "BLOG"! at [<phabricator>/src/applications/transactions/worker/PhabricatorApplicationTransactionPublishWorker.php:133]

That error likely means you need to add a new PhameBlogTransactionQuery class. You can look at PhamePostTransactionQuery for an example -- it's pretty straightforward.
