You just never know whom you end up infuriating. So although it is true that some bloggers make controversial references in order to get attention – and some traffic – you will be better off avoiding this.
Inappropriate remarks
Don’t attack others on your blog. It still isn’t okay even if you don’t name anyone. Your blog is not a weapon and freedomofspeech isn’t always appropriate everywhere. Even if you genuinely hate certain people, keep it private.
Also be cautious with humour. What is funny to you may be offensive to others. If you feel like you have to use some humour, make sure it is amusing in a light and fluffy sort of way. Don’t target individuals.
