My experience with decentralized social media these past 4 years is telling me that once we build they will come.
It's hard to invite people who aren't curious by nature to platforms like Gnars and Skatehive, they proly don't even bother too search as you said, too lazy.
The only solution is to guide them to decentralisation with actions, not words. Make them wanna come here, don't ask them to hehehe.
We're still very early bro but we're making things happen. It won't be easy but we'll make it, all together as a community and for the love of skateboarding.
