Perhaps it is my own pet peeve, but I've never really liked that they mashed all the various etiquettes into one skill now.
Sure, you can specialize and get a couple extra dice, but just dropping 6 skill points into the Etiquette skill means you can handle yourself in any situation.
That rubs me wrong way. In 3e, I had a house rule that kept each etiquette as a individual skill, Street, Corporate, Organized Crime, etc - but you could raise it using karma as a specialization (so as not to punish the players too much.)
The result was the runner who was brought up in the barrens and dealt with the people who hung out in that area would have Street Etiquette, and he would be able to buy illegal weapons, score drugs, know who to talk to when he needed info, etc - but if you put him in a boardroom or in a Native American tribal council he would stick out like a sore thumb - I don't care how charismatic he was - he just wouldn't know the nuances and body languages to fit in.
Similarly, the runner who came from a corporate background would have corporate etiquette - and would have the reverse problem.
In many cases, players took multiple etiquettes, but usually a primary and a secondary - so that runner from the barrens might have a street etiquette of 5, and after a while of dealing with corporate drek, would buy a corporate etiquette of 2 or 3 so as not to stick out so badly.
It is just to homogenized now for my tastes.
