…no matter how many people you friend on Facebook, follow on Twitter, or connect to on LinkedIn, you can truly be friends with only 150 of them. If you have more than 150 people in your social circle, then you have to accept that the quality of those relationships is rather poor…

The article suggests some ways to maintain close relationships with true friends, including:
Make a list of 10 close friends (parents count as 1 friend). Once a month, send each of them an email and schedule a time to meet, Skype or chat on the phone (aim for in-person chats as much as possible). Set aside an hour to catch up on life, work, hopes, disappointments and goals.
