How does wordpress work?

[AK]

I have a tumblr right now (art blog), but it seems like it's more like the myspace of blogging. I could be totally wrong, but it seems like more so then actual interesting blogs there are people just reblogging and liking blogs to gain followers rather then providing meaningful content. To me it seems more like high school popularity game. I've only been on it a few weeks. Am I right?

I've only been on it a few weeks and I wanted something a bit more serious. I have a video log on youtube to partner along with my blog. Since I just started blogging, I haven't posted that much content yet so it's not too late to switch. I'm thinking of switching to wordpress. How does wordpress work? It is just a posting platform? Do you have to find people to follow you like on tumblr? How do you generally get readers on there?
