What is the most sensitive issue as a Blog publisher ?

Tweet

Good morning friends!! During the last two days, I have visited more than 6o blogs of my friends in myLot and reviewed. Can you please tell me what is the most sensitive issue you have faced as a publisher ? Is it traffic? Subject for writing? Time to blog ? The links ? or the technical support ? I am worried about the search engine optimized keywords and now researching on it. Let us share our knowledge as descriptive as possible.
