Hey just FYI, there are MANY alternatives to steemit.com that all interact with the same STEEM blockchain. Busy.org is one such website, it has been running smoothly the entire time that steemit.com has been having nonstop issues. If you want to be able to post, and upvote, and comment, etc., without transaction broadcast errors - check out busy.org or one of the many other 3rd party alternatives to steemit.com. To be entirely honest, steemit.com is pretty much the worst option as far as reliability and user-friendliness when it comes to all things STEEM. Good luck!
