What do you think of this new trend in society?

[T]

Where people post pictures on twitter of the food they've eaten and the clothes they bought and places they shopped and cars they drive? I don't really like it, but would like others opinions. I mean, if you were someplace thats exciting, why not, but some of my friends would take a picture of starbucks coffe and post it up there...or food they ate at any restaurant. I think that is a bit extreme...and why even waste time doing it? Is it a symbol of social status? Cause to me only it only portrays a mindless customer. Plus, you're advertising someone's product without getting paid...what do you think?
To jacqui: hahaha, if the best part of your life is having a sandwich, then maybe you should just die? No wonder half of the nation is obese...Now, having fun with friends is other thing, but then why not taking pictures of you and your friends, rather than of a lonely cup of coffee? I think that's pathetic. But, thanks for your input
