I feel like people spend more time migrating blogging engines than actually blogging.
Writing in Org mode has really reduced the writing block for me. I'm so glad I switched from Octopress to Hugo about maybe 2 years back.
I used Ghost, Octopress (which was basically Jekyll), a variety of SSGs that I tested and never got to deploying, and then Pelican.
Since January 2016, though, infrastructure work basically stopped and I just write things, and occasionally dink the theme.
