I've taken the leap after nearly 5 years from Postach.io to Blogger. My blogging has been sporadic, and I resented having to pay $50/year for a service that I was rarely using. Also, I was getting frustrated by the formatting issues that seemed always to arise in the translation between Evernote and Postach.io. Lastly, as I think I will soon move away from Evernote this seemed like an obvious first step.
I plan to move as much of my digital existence as possible to Google. I know there are privacy issues with this, and there's the risk of having all my eggs in one basket - but Google's stuff is free and, for me, this is significant. The analytics are more intuitive on Blogger. Also, Grammarly now works across the Google suite of products and so I should be spared some blushes :-)
It's going to be a mammoth task transferring material across, and I may lose my Disqus comments (I've yet to investigate that problem) but if I tackle a post a day it should be manageable.
