Visiting friends does help keep your sociability levels up. It takes less time if you tap quickly on three items and then go straight back to the friends list. You don't have to wait for the "you've been a great neighbour box" your XP,cash and hearts will still be added.

I've been wondering this for ages and been trying to work out if they are added, thanks, this will save me a lot of time! :D
