Clearly, What it has and what XenForo doesn't is very little.
And what XenForo has and that example doesn't have is a lot.
I feel like the OP knows that too.
But he just wants to get the feeling of social media website when he's browsing, because most people are familiar with the interface and the same time he wants it to be a forum.. Of course, like a perfect forum which has tons of tools and features just like XenForo.
Okay, okay, he might want it to be the exact Xenforo

or he wouldn't ask about the ROADMAP of xenforo this year
Part of me agrees with the idea of giving a familiar interface for users. I remember
@Kier also had mentioned it in a xenforo insight episode, he recommends us to use New Post as the homepage route as opposed to forum view page, because more people are familiar with social media type interfaces.
Well, which features would we need to cannibalize /implement / ADD? Or whatever you call IDC
I guess that the contents of the one in the example is based on #hash #tags
It doesn't have nods tree, right? So it looks more like Reddit?
The XenForo has given more than enough powers to the add-on system so a skilled developer could easily build an add-on create a bridge / link / relation between a new hashtag entity and nodes.
Then all you need to do is install that add-on and a skin (style) Which would give a feeling of that social media site.
We also have a powerful criteria system too. We can extend it and give permission or user promotions to specific members so they can create hash tags / nodes.
I remember the
@ThemeHouse @Mike Creuzer and his team have had developed an amazing add-on called Topics, but unfortunately they have discontinued that add-on. I was planning on installing it too
