If you're doing it purely for additional social exposure... a WordPress or Blogger blog is a good way to go; generating income from those is a long tedious process, however... until you have a following of 1000s, income is minor. It's a bit like having a YouTube channel... until you have 1000's of viewers, it's slow going.
I still enjoy blogging elsewhere, though... mostly niche stuff there doesn't seem to be that much demand for on Steemit.
