Depends on your "freind circle", its rare but if you are in a group of your same interests, it definitely is more efficient and you advance, see more, understand more quickly because you share vaste amt of information. But if your friend circle is all gossips, then, you will have gossips to work with, maybe important if you are a in talk hosting business. :), but i noticed that people w more random information , random in the sense tht you did not have to actively look for it yourself, they probably is more stimulated in a general way. So gd, especially if they could work together tightly or loosely. Someone isolated is definitely not as potentially in a gd position to react to troubles ahead, to put it as simply as that.
