I admire people who have the foresight and courage to pick a practice area and learn it, inside out. I greatly admire those who share the knowledge they have to help other lawyers and the public.
Here is a fine example: Dog Bite Law by Kenneth Phillips. He limits his cases to representing people who have been bitten by dogs and "accept [s] only cases where a person has been bitten in the face, or has become disabled — or where a person has been killed."
Kenneth shares lots of information for victims of dog bites, down owners, parents, journalists and other lawyers. He also sells what appears to be a very comprehensive form book. He also sells videos and books for lawyers. For those who have relatively minor cases, Kenneth sells forms to aid the injured party in resolving his own case.
