I was using Wordpress to blog when I first started on steemit. For the most part, you can make your whole blog post on Wordpress and just copy and paste the html over to steemit. Maybe you would have to add a few little tweeks to get things looking right here and there but not too much. You can even store a few Gig's of images there so it's an image host as well.

This was before I got used to markdown. I just use the steemit editor now that I'm more comfortable typing out all the formating for steemit. It's quick once you get used to it but it does take a while to learn all the commands you can use off by heart. The steemit editor could be so much better though. I wish you could have some shortcuts for adding links and formatting while still be able to use the markdown code.
