To me, it was the astounding amount of interactivity between the community.
At first I thought this was temporarily caused by the whole migration from the R site. But, just out of curiosity, I signed up to Mastodon and have enjoyed myself just as much as here.
Most of the Lemmy post's / Mastodon toots have almost as much or more comments / boosts than upvotes or favorites. It feels so organic and makes me realize how much these huge companies employ technics to pretty much force to interact the way they see fit.
It reminds me of that good old saying "you are not immune to propaganda", well I guess neither I nor anyone is immune to psychological tricks either.
P.S. I also love the fact that since there isn't pretty much any money involved, most opinions and interactions are genuine. Like, who is gonna pay this dude to advertise a book through BookWyrm? That increases immensely the odds that said person is being honest with their opinion of that book. It's amazing.
I absolutely LOVE the open source/federated aspects of things! I think it's just so cool and interesting to me how it all works! :)
It took me a while to wrap my head around, but once I got it I'm loving it! Especially now the issues with the massive influx are starting to go away. We're on lemmy right now, right? But you and I are both posting from kbin, and you posted 3 minutes ago, and I can see it, and my reply is getting through. This was NOT possible yesterday.
It's amazing to me how fast its all progressing! I really love this stuff and am so glad to see it taking off as fast as it is!
It gives me hope for the future of the internet, even if the average layman never learns or cares about it all. It's interesting to think that the Internet started this way as well, it was a complete nerd thing at first and nothing like we know it today.
I hope I can contribute to either kbin or lemmy once I find some time, probably Lemmy since I know Rust and nothing of PHP. Perhaps it can be a fun way to learn PHP as well though
