Sabrina,
Yes, I can see the comparison with FB but ultimately this site is thankfully much better. As it's been said, even though we may not have met in person, the eloquence of writing, the way people here express their thoughts, opinions and feeling gives us all an insight into them as a person.
Our strengths and frailties are laid out for others to see in a way you don't encounter of FB. Here you'll find a level of honesty not found on FB and also a lot less trivia about cat's, dogs and idiots falling off roofs.
