Ah yes, the Social Crutch skills.
I tend to concur with the use of Gather Information to represent abstract trolling for information. Ie. "My character spends the day hitting the taverns, looking to learn more about Lord Whatsisface"
It seems like, in most cases, all the social skills end up working best when used in this fashion. Basically the player states an attempt at an effect and rolls the dice for the outcome. As opposed to the player role-playing the encounter to see if he is successful.
I almost think the two methods are contradictory. Basically, as a GM, you should decide which method you will use and eliminate the other. Like role-playing encounters and dislike "rolling for it" then eliminate the social skills. In this method, it would be up to the player's role-playing skills and DM abjudication to determine what happens next. The Perform skill might be the one social skill I'd keep, as I would assume that playing a bard does not impart any actual musical talent...
Not comfortable with role-playing, then simply use "roll for it" for all resolutions. You could still probably role-play some encounters that the players are interested in, but if there was an outcome involved, you'd resolve it with dice.
