I came to know about a blog's reading level from this entry at Temasik's World. By clicking at this link, blog owners can rate the readability of their blogs. And the result?
Apparently, my blog is at the postgraduate level. Notice the test tube, atomic stucture and rocket.
Afterthought: I tried this tool for my other two blogs which use mainly Malay language, and the outcome is that those blogs are at the genius level. My guess is that if the language used in the blogs couldn't be understood by the tool, it'd regard those blogs as having a high level of intelligence. To quote Homer (Simpson, not the philosopher): D'oh!
Treat the tool as something fun, and it shouldn't be taken seriously.
