Has it ever occurred to you that a social networking community could be so diverse? Are you really reaching the right audience, and if so, are you reaching them effectively? Are you sure that Twitter is the right community to be marketing your blog on when there are sites like Facebook or Myspace that allow you to become even more personal with your audience?
Companies are seeing that the best way to conduct themselves online is to speak to their customers directly using these social networking sites, Twitter being especially useful for this. It increases the reputation of the company, gets them positive reviews and shows that they really care about the customer. It also gives a human face to the large corporation, meaning that customers or potential customers will feel much more comfortable coming back.
