Some people do have the knack for writing and others don’t!
This proves that not all bloggers are writers; let me state that they weren’t all that bad, but there were lots of room for improvement. (Just think of my statement as a form of constructive criticism; I am not being biased towards anyone).
I truly hope that my observation doesn’t discourage anyone from writing, because that would mean less for me to read whenever I explore my WordPress Reader.
By the way, if your goal is to be a writer and you are not good at it, you might as well continue to practice.
Just remember that readers can be quite picky and a little judgmental and it is impossible to please everyone of them.
