I am always behind the game when it comes to technology.  But, at the urging of one of my kids, I have  opened a Facebook account.  In the short time I have been at it, I have seen just how much time can be wasted going here and there on the site, from one friend to another, etc.  Then, to top it all, another son just introduced me to 4 Marks.  4 Marks is a Catholic social networking site and I actually think I am going to like that one better.  For one thing, there is so much to learn about the Faith.  For another, the advertising is not offensive and virtually all the links are to topics which are of interest to Catholics.  Give it a try at 4-Marks, but decide in advance not to spend your day there.  I am going to have to get a timer and stick to a limit.
