I really don't see any use for it. Is it just a way to make someone's day? I honestly have not the foggiest idea in my head. If anyone knows could anyone tell me? Maybe? Thanks so much
If you really like somebody's coding or art, the follow button is a way for people to see when that person publishes.
Yes. And you can see it in the following tab. Or, when I joined, a tab by activity and where levels were. Before the + button
Pressing the follow button means you really like their projects and it helps people show support
Pressing the button means you can check your tab that says following to see if that person has published something new.
