Future of this blog? Login and comment system?

Adding a backend to this site?

I want to have my own comment systems and notification running on the site. So viewer can subscribe to their interested topics.

And, this account will be using my Intenca project account. Because most of my articles viewer should be a learner (I guess?), I want to build a brand of learning or studying suite. They will be free to comment and tags subscriptions. Or, maybe even have some apps on this site they can use.

But, I should build the suite first, no matter what.
