A lot of people in the comments are suggesting alternative small talk, like "tell me what you did this weekend" or "tell me what you're about (?!)". I don't understand the need for any of that. You're meeting in some social environment: talk about that. If it's a dinner, talk about the food, or the host. If someone has just given a speech, talk about that. If you're at a sporting event, or a mediaeval reenactment event, talk about that. In extremis, talk about the weather. There's no need to either deliver or request an elevator pitch of any sort, on any subject, is there?
I moved from San Francisco, where it was common to ask people "wnat do you do?", to South Carolina, where it's considered a little bit rude. For me, it was a painful transition; I no longer find it easy to get into enjoyable conversations with new people.
I've always found it difficult to talk about, e.g. food. "Isn't this food great?" "Yeah, it's delicious"! Similarly with the weather, or any other conversation where you're basically just repeating what's obvious to both of you.
Of course some people prefer it this way, and genuinely enjoy small talk -- they don't feel a need to be talking "about something". Far be it from me to piss on their parade. But if you don't understand this need, consider yourself lucky.
Generally, small talk serves to get people started: it makes the conversational juices flow. More interesting subjects may well then arise. (Or not, in which case, the brief conversation comes to a natural end, and you talk to someone else.)
Finally, a normal comment. Reading these intricate strategies on how to talk with someone - it’s like being at a recovering social recluse convention sponsored by Social Neurotics Inc.
