Lock in new friends
You may not want to do this with everyone but when you meet someone important or special, it’s important to lock them in after you’re friended. Send them a personal note about meeting them or about something in their profile or homepage. Then if they write back invite them to a chat.
Its worth inviting them in the beginning because if you don’t know them enough to invite them now you won’t two weeks or two months later. It’s worth doing this because it’s easier to turn a new friend into a good friend than to turn people you don’t know into good friends. And it’s really the number of good friends that really counts not the number of total number of friends.
I think the trick here isn’t meeting new people but turning new friends into really good friends.
