comments aren’t a thing with writefreely
What do you mean? You can look up any profile in the form of @[email protected]
from apps like Mastodon, Friendica, etc.., see all posts, and comment regularly.
Is the fact that there's no link or embed of the comment section at the bottom of the WriteFreely page that is bothering you, or am I not understanding?
On a side note: if you are really choosing how to build a blog (like it seems you are), and are not taking the first free managed hosting provider you come across...
I would think twice before using any server software instead of keeping your site static. Having a server software that's more complex than simply serving static files will do more harm than good in the long run: more security flaws, you have to always keep the thing updated, higher resource usage, and hard to make your content survive the test of time (backing these things up is hard and when you do, you have a database file, not some plaintext ones)
