For places where I list groups, I list them because groups have members. One could consider the connection rating the amount of influence that person has within that group. For example, an organized crime connection could be anywhere from a hitman to a small boss to an accountant. I can break some of these out if you want, but the list was getting a bit long. I may re-edit this later. I think I trimmed too much stuff.
Note that there is also some overlap. An identity broker has some overlap with a forger and a hacker, for example. Smuggling appears twice.
