Me and my friends do the same but I don't think it's lame. I love it and can't imagine how things were before smartphones. Am I the only one who likes this social development?
I find it even more awkward when i visit my cousins and they post and tag me on facebook. They will later ask why i never liked/replied even after seeing me 'check facebook' on my phone. I want a less-posted life thats why I'm quitting most social sites.
With a preposterous amount of Facebook users all across the world, I think we are all projecting our personal experience on millions of others to make a value judgement. I personally get nothing out of it. How is it positively changing your life?
