@grishka I disagree that a social network blooms only on Facebook / Whatsapp model. Many users on Twitter, Instagram, etc., enjoy finding strangers and new content by interests. A very large ammount of social networks is built on this concept. Many still use VK specifically for its communities that unite random people. Telegram became popular in part due to its chats/channels. I wish you luck with your idea, but also encourage you not to dismiss the importance of good UX connecting strangers ;)
lostinlight, I do have groups for that purpose. Yes, connecting strangers is important, but — as I said — secondary. Being able to find strangers with common interests isn't what locks people into Facebook/Instagram/Twitter/VK/whatever — it's the connections with people they know IRL. And thus, to liberate these people from these greedy creeps, we need to provide for that use case and make it as effortless as possible to switch.
