theories welcome...

So reading one of McSweeney's lists sparked an idea that has been rumbling around and I am wondering if any of you Facebookers or non-Facebookers have any clues as to why this is the case...

It seems very popular for people to post picture and status updates that seem to no take into account the fact that other people will be reading/viewing their postings. For example how about the guy who added a bunch of photos of him and his buddies drinking their faces off and then adding his mom as his friend. Or how about the pictures of the former spouse in an embrace with the new beau even if the marriage is over...

Hmmmm

I am not sure it boils down to just a lack of etiquette or tact - I wonder if it is a deeper, scheming evil side of....

Well you can clearly see that I have no clue

So if you have any ideas fire away...
oh and here is the post from McSweeney's
