Basically, what the tool found out is that what I have been writing about in my blog requires only Primary or Elementary School education to understand my blog. Could that mean I am an excellent writer and I am able to explain complex topics in simple terms? Or is DB2 easy to understand (and administrate)? Or is it the database topic in general? Maybe I should be more technical to raise the level and make reading this blog more demanding. On the other hand, what is the audience I am trying to cater to...?
