I'm actually working with both .org and .com versions.
One runs on the usual free Wordpress site for my blog, and the other runs on GoDaddy for my book's website.
It takes some work to get the features I like on both. I needed a plugin on Jetpack to give one the features that came with the other.
For the life of me I can't remember without checking which version is .org and which is .com.
I am quite proud of myself that I've turned out a reasonable product in both cases without having to touch code with my bare hands.
