At Opera we built MyOpera, a community site focused on serving the Opera community. It reached 35 million users and 35 million monthly visitors.
After I left Opera, MyOpera was dismantled and Opera went for Facebook and Twitter instead.
At @Vivaldi , we have built Vivaldi.net, with more than 1 million active accounts so far.
We have now made our own Vivaldi Social Mastodon server.
When you make your own server, you are more in control.
Are people learning?
@jon only time will tell, but I do hope in the coming years, social media turns to a more decentralized approach.
