I admit it...I love Facebook, Twitter and TF - would feel lost without all three now
Originally I used to have different people on all three.....Facebook was more personal friends, Twitter few people I knew but mostly talking to total strangers but in recent times I seem to have the same friends on all three now
But, they are all very different....I still feel as if I'm on my best behaviour on Facebook, feel as if I can say whatever I want on Twitter and TF...I always try to be careful what I say

One thing that I do love on Twitter is how I've interacted and become friends with people from TF who I had never really had contact with on the forum before
In general though...I love any way to stay in contact with friends from around the world and to hear other opinions...all three sites are great!!!
