Wow, it seems you learned pretty quickly. It took me a bit longer to get to the difficult 9x9s.
I've made a series of videos of how to solve an easy kenken, and how to solve a difficult 9x9 kenken that doesn't even show the operation signs.
You can check them out at Kenken at the Math Mojo Chronicles.
You've done a nice job with your blog. Keep up the good work!
