"Concise" is one of my favorite words. My ARTicles are meant to offer concise thoughts.
One person also told me several times that "Brevity is the soul of wit." It got stuck in my head until now.
Applied to writing, I learned that if you spare time building up good intros to hook the reader to continue reading, then it's your next task to get straight to the point while keeping the substance fiery until the end. It would then be an effective writing. I have yet to practice more on those values.
In the mean time, blogs must be concise if it doesn't have too much to say.
