On the other hand, isn't this position essentially saying that because the things in your life are similar to others and not surprising, they aren't valuable and worthy of documentation?
What's wrong with "look at me?" Am I not worthy of being looked at by my friends because I haven't done something remarkable? Just because my kid isn't really all that different from every other kid, or thousands of other people were also at that concert (and my photos are mediocre at best). . .
And if I share something actually remarkable that I've done, it's just "bragging," right?
I don't log in to facebook very often. But when I do, what else should I expect to see but what's going on in their lives?
My instinct is the same as yours--to hold back and be private. To not share my life with others, because they might be bored. To not document my everyday triumphs and failures, because they're not really that different from anyone else's.
But I have a sneaking feeling we might be wrong about this one. Maybe our boring human lives are worth documenting and sharing.
