I remember getting pulled into Facebook because classmates tagged me in photos. Then when I signed up, it was extremely useful because you could see and meet other people in classes for study groups, etc. It was also great at delivering status updates, well at least until people started saying "John Smith is." lol. The other powerful thing Facebook did that no other social network did was handle growth. Friendster and Orkut, they were painfully slow to use even in their early days.
