Yes, absolutely. People are like me and find new good people by looking through intro posts. I go through them usually every single day. You will get a good amount of quality followers from a good intro post.
There's more to it than that though. The more you share about yourself, the more people will be willing to follow and support you. Some people don't want to network or engage, and that's their choice.
They will have a harder time being successful here though.
