How to earn money through blogging?

I am waiting for an expert to answer your question, because I also wanted to know how they do it. Though, I've read from a lot of bloggers that their write-up didn't really get recognized right away, until such time when the topic they wrote about was in tuned with the season. For instance, you wrote about Jeremy Lin back when he was not famous, let's say 2 years ago, then by first quarter of this year 2012 people learned how awesome the guy is and start searching for information about him. Luckily you wrote a pretty good stuff regarding the guy and that's when you get traffic to your site and that's when you earn money.
