I just wanted to apologize to the community for posting my last blog post several times. When I attempted to post it I received a 'transmission broadcast error' and the website behaved as if it didn't publish my post. So I tried again... assuming that the steemit blockchain was just congested or that the code on the steemit.com site had a bug.
That still didn't work, so I tried yet again a couple of hours later and got the same response. Upon researching the issue on the steemit.com GitHub channel, it appears that this is a known issue that was previously unknown to me :)
So I'm sorry for the multiple posts. If you create a post on steemit and receive this error, check your actual blog and see if it posted in reality despite the error message that you received.
