Unfortunately, the Selenium site itself does not provide much educational material.
Judging from your blog, you are more interested in Selenium as a Java API than as a capture/playback tool. I think that is the right choice, but it does require some programming skills. Your blog has articles on elementary Java programming, e.g. "Branching Statements in Java for Selenium Automation". I do not know whether that means you are new to Java as well. I will assume that you are.
Some people seem to like using "page objects" in their Selenium automation. I am not one of those people, but a Google seach should turn up plenty of references.
