In TS2, everytime you moved into the house, three neighbors would show up to welcome you. In sims3, it is like Pam said, maybe 1 time out of 5 that someone will come visit. So it does not happen very often. Well, if you happen to think about, how many people come visit you when you move into a new neighborhood. Back in the day, heck when someone new moved in, someone might bring a casserole or cake or something and they had welcome wagon. Not so much now a days. We have been in our house five years. The other day someone came over to welcome us to the neighborhood, I thought, where have you been, lol.
