Thoughts on Facebook

Facebook is so fun. I've reconnected with several people that I really did wonder what happened to them. But it's so odd too. I have almost 200 friends but hardly anyone posts, maybe a dozen or so people regularly. Even weirder is that while almost no one comments on my posts (maybe a half dozen people), I've had several people say to me in-person that they liked something I posted, an article, or a photo, or whatever. But why didn't they say that online? It's like they're unclear on the concept - that's what the "like" button is for if you don't want to take the time to comment. I just don't understand - why get involved in social networking if you aren't going to interact?
