Just because you might be friends with someone doesn't necessarily mean your child when be friends with that person's child. First and foremost, don't force it. Your child will only resent you in the end if you make him spend time with someone he doesn't particularly care for. There's nothing wrong with introducing him to new faces. However, let him take the lead when it comes to building lasting friendships.

At the same time, you still have a responsibility to ensure that your child is playing with kids who have similar values. In other words, you probably want to prevent your children from hanging out with kids who swear, steal, misbehave and have other habits you don't want your own child picking up. Always be aware of who your child is hanging around.

At the end of the day, what you don't do for your children is every bit as important as what you do. Sometimes a more hands-off approach actually will benefit your child.
