There are a few solutions out there for adding comments to your site without the need to make your own commenting system. So why bother with this?
Part of your site
The Jamstack comments approach makes comments part of your site. You choose how to include them within the content of your site. And since you bake them right into your pages, they will appear in search engines.
Feel free to comment on this page using the form below. Keep in mind though, that this is an example site, so it's not the place to make a big grand political gesture. Try it out, but be nice. (All comments are moderated anyway)
