Yes. I think having two or three very close friends whom you see often is vastly preferable to having fifteen or twenty friends you rarely see (the "see often" bit is probably the biggest challenge, especially once you have children). Conversely, I have found in business that having an endless stream of acquaintances with whom you are on vaguely friendly terms is extremely beneficial.
