Why do people seem to use Facebook less and less?

[Paul P]

I think it's due to most people being overwhelmed by FB.

I only add close friends and family, and I fretted when my friends list went over 50 people (it's about 55 now).

A lot of people will have hundreds of Facebook friends. When you have hundreds of "friends" it is easy to lose track of all that information. It is easy to get overwhelmed and just not care about it anymore, so you quit checking.

I mean, if you have 400 friends that's more than a birthday per day. It's easy to get burned out from having to wish so many people a happy birthday, so they just quit doing it altogether.
