Comment support is fully integrated into WP Medium.
Simply enable comments on your posts and pages using WordPress and they’ll be displayed beautifully to all your visitors.
While comments aren’t for everyone, they’re a great way to get feedback from your readers. They’re also great for SEO because they help add extra content to your page (WP Medium is great for SEO by the way).
If you don’t have a lot of readers, or just don’t want to have your readers comments on the page – they’re really easy to turn off.
This themes comments are fully powered by the native WordPress comment system, so you can take advantage of all those powerful controls (including Akismet for spam prevention).
