Yesterday was Ash Wednesday and the beginning of Lent, which is a time for fasting and reflection.

Last year, it was all the rage for college students to give up Facebook for Lent.

But these days, it's not just kids who are hooked on the online social network.

It has become wildly popular with adults over the age of 25.

So this year, it is just as common for middle aged users to say they will abstain from Facebook during Lent as it is for the college crowd.

This shows how popular and how addicting networking sites like Facebook and MySpace can be.
