We are all guilty of this at one time or another. However, fluffy writing can cause us to lose a reader's attention. If you are writing an article about apple picking sentences such as "picking apples is fun" or "I bet you'll have a blast picking apples" are fluffy and unnecessary. Get to the point and don't overuse adjectives. For example, don't write "when I visited the bright and sunny apple orchard". Just write "when I was at the orchard". I think you can see where I am going with this. Get to the point and stick to it to avoid fluffy writing.
