Blogging

So this blog is for a school assignment. I never have been good at blogging. I have tried a few times, but my blogs have always died away rather quickly. I never have anything smart or witty to say. How do certain blogs get popular anyway. I mean, I understand if it is the blog of an author or a musician or something, because people google them and then their blogs come up, but those random people who blog and vlog, how do they become so well known? Do they post their links everywhere or just sit back and wait. I think that they probably start off posting their links places, but then it eventually spreads. I wonder if I could find a blogger who would be willing to do an interview...... *goes off in search of blogger*
