If you don't add people to your connections, no one will know about you on Tripu.cz. The people you connect with and whatever you comment on, or vice versa, can help you get visibility. You comment something to someone and other people see it who wouldn't normally know about you. It's a great way to spread awareness about you.
Another option is that you join a topic group where you can add posts, pictures, videos, links to articles and discuss. Groups offer the opportunity to network with people with the same interests.
