It certainly makes some sense, to me. I believe Fe, Se, Ne and Fi (to a smaller extent) are the "people" functions, and somewhat in that order. Extroverting with the world of things, is what I'm still fuzzy about. I don't spend a lot of time "in my head", but I do spend a great deal of time alone. However, I'm usually doing something (forums, cleaning, organizing, working, watching movies, tinkering with gadgets, chatting, reading, etc.) I believe this is actually considered to be using an extroverted function (and the way a great many IxTx types usually extrovert), but I've not come across many articles on type, that discuss extroverting in terms of interacting with external objects, that aren't other people.
I've seen nothing that explicitly states TeSi or TeNi would have a particular draw to people. The two ESTJ's I know are pretty sociable people, but their social interaction is typically very shallow, in the sense that they always have a purpose for it; initiating business contacts, directing others in a project, gaining status, etc. They aren't close to many people and have no "emotional" based desires to interact with many. It would seem, that if socializing didn't offer them these logical gains, they would have little to no use for it.
