Now let's filter out bots, low quality trolls, NPCs, and content that isn't easily searchable. It's definitely an interesting diagram, and, though it is fascinating, I think its a 1 dimensional view of the social space.
I prefer to engage around ideas and topics, rather than specific users or content producers, so having a good search and topic based boards or groups immediately puts a site miles ahead for me. Reddit and Lemmy excel at this, but some of the others leave a lot to be desired. As someone who used FB to organize and manage a topic based social group in real life, with a Facebook group of 1000+ participants, FB has some good groups, but the interface is absolute rubbish and I would migrate to just about anything else if I could get people to move.
I guess my point is that we lump these together as "social media", but that's a broad category that holds some very distinct subcategories that excel at very different things.
To add to this, a supermajority of reddit users are inactive. Recap has shown that even with minimal activity, you end up in the top 1% of reddit users.
Based on that one can calculate that 99% (provably more but reddit recap doesn't go smaller than 1% on display) are inactive accounts, which means reddits true size lies at around 5 million or less. Less than 5 times Lemmy's size.
There's a reason why mentioning the word "Lemmy" on reddit gets you a shadowban now. Because they're legitimate competition.
reddits true size lies at around 5 million or less. Less than 5 times Lemmy’s size.
Lemmy doesn't have 1.5 million active users; that's how many active users the Fediverse as a whole has; most of those are Mastodon users. Lemmy has around 32K active users. So if your 5 million number is right, Reddit is around 156 times larger than us.
