niche

"I have always believed that the “niche” law blogs—those tracking a particular area of law—are more likely to be followed regularly than are the more general blogs, law student blogs and the like. The average user will not be a voracious reader of blogs, but he or she will, I think, take the time to receive information useful to his or her practice, whether it be practice area-specific or related to the business of running a law practice."
