Can this blog be monetized? Originally it was never meant to make money.

The Blog

http://www.robotcrypt.com/

I know when creating a blog or site for monetizing purposes that a lot of work and research go into it before a domain name is even payed for. There are several strategies and different types of prep work involved.

I'm wondering if a site or blog that was never created originally for marketing purposes could be set up to make some money however.

I started this blog as a way to write for fun and creatively while talking about some of my favorite things. It was, and is, a good break from content writing for other people, allowing me to write about stuff I really enjoy, or to practice humor writing occasionally.

I attached Ad Sense but that was simply an afterthought, and I think I've made a little less than $20 without putting any work into it.

Can anyone take a look at this and see if any monetizing ideas jump out at you? Again, because I had never planned to make any money off the thing in the beginning I didn't do any keyword research or anything of that nature.

Robot Crypt is the name of the blog/site. I am unable to post a link because my post count is too low.

As explained I am making no money off the site at the moment nor do I sell anything there currently, so I assure you it's not spam. Just trying to get people with a marketing background to provide any ideas. Thank you.
