Big words especially considering you can't search through the people who "like" the same interests as you in Facebook. What's the point of social networking if I can't actually connect with anyone who is interested in the same things as me?<p>Social networking is about connecting with new people, not a virtual front end for people you already know...
"The definition of groups is... everyone inside the group knows who else is in the group"<p>Pretty good point in my opinion. Maybe groups are a better solution for people who want to share with a limited number of friends. It also is much less work since only one person has to set up the group.
