Gear
One of my hobbies is photography. A common subject in books and magazines on photography is what gear and work flow does the author of the book or some well known photographer use. This kind of information often is a great guide in sorting out what equipment you should or shouldn't have. If you learn that Joe the Famous Photographer uses the cheapo wide angle lens instead of the $2,000 version you can scratch that more expensive lens off of your wish list.
Gear and work flow have now hit the attorney world. There is a very interesting post here at Ernie the Attorney on those subjects. Included in the post is a link to a pdf document that lists and explains his work flow and the equipment he uses. If you ever wonder why in the world you would want to use a certain type of gizmo, you might find out in a post like that. I hope there will be more from other blogging attorneys in the future.
