I used reddit a little bit, but never really took to it much, and if so, only pretty late.

But I've always liked old school forums and other link aggregator type places like HackerNews, and of course ye olde blogosphere. So when I came to the fediverse last year on Mastodon, and being enthusiastic about the whole idea of a broad interoperable network of FOSS internet spaces, I looked around for things other than microblogging, which I personally find to be the worst form of social media. There are blogging platforms, which are nice, but when I found Lemmy I was immediately excited. I joined once I had some spare time, and poked around trying to get people to use it more, in part because it complements mastodon well, and because I think it's a better form of social media.

Having now used mastodon and lemmy for a bit of time, I'm more convinced of my opinion of microblogging.

In a world, which I hope the fediverse gets to sooner rather than later, where multi-paradigm or multi-platform social media is easy to do, I think Reddit-style forum/link aggregator platforms (+ threaded comments sections) with personal micro and macro blogging on the side and privacy respecting chat rooms like matrix integrated would be the "killer meta platform" of the fediverse.

People will vary in what they use most, perhaps over time and context too. The killer feature will be being able to move across and leverage these different formats easily. Forums for public searchable discussion. Microblogging for public but personal conversations. Chat rooms for closed conversations amongst trusted people. Macroblogging for long form authorship.
