It took a while, but i finally figure out how to add comments into this particular website, using Giscus as the comment provider (?), instead of using Disqus.
Before i resorted on using this provider, i went to look for another comment provider, because using this means you need a GitHub account just to comment, which would probably limit the audience for solely just to make a comment in this website.
But since that other providers need you to self-host the aformentioned provider, and this provider either, which this one need you to pay for a subscription to use it cloud service, which for obvious reasons make sense for the subscription model (server funding).
The first option probably wouldn’t work since i’m hosting this blog via GitHub Pages, which (probably) might not work, or maybe i’m wrong about this, and the second option is the same as the first one. So i’m left with no choice but to use Giscus instead.
But anyways, at least you can finally comment in this blog, which means you can finally type whatever you want to put down there! And i’ve finally did my previous promise i said in my previous posts.
And also, adding a search and share button was somehow that simple. Apparently i just didn’t read the wiki + theme’s source code for its config options.
