You know you have been online too long when:

• You can’t add anyone new to your AOL address book. The pre-set limit is 5,000 and I have reached it. This morning I had to go into my address book and delete a bunch of names.
• You reach 5,000 friends on Facebook. I bet I will reach that number in less than a year as I am already closing in on 3,000 “friends”. I made a mistake in that I add friends with the criterion that we have at least five mutual friends in common. Well, guess what? As the denominator gets bigger, the chances of our network being interconnected increases geometrically. Hence, I have lots of friends now on Facebook.
• You are still in the top 5 percent of connected individuals on AIM Fight even though your friends are getting older and aren’t as connected as much and use Facebook messaging more and more and AIM less and less.
