For me, if it is something that I would not want my grandmother to read or see, then it doesn't get posted. I don't need that sort of information forever on the internet.
I compare FB to what I tell my students on the first day of school, if you can't say it in front of your grandma at church on Sunday, then you don't need to say it here.![]()
Facebook status updates should be things that you'd share with friends and family. One of the big problems in our society, that Facebook helps address, I believe, is social isolation stemming from urbanization and perhaps even industrialization.
The problem, I suspect, is that some folks may either not be aware of, or be too casual in their use of, the privacy control for each status update.
I have my connections divided up into a number of groups, and actually have my default privacy set to four or five of these groups. Only people in these groups will see the message, and generally, I click on the padlock and delete one or more of the groups each time, often just leaving the one group of people who should see that specific message. The reason why I do it this way is a lot easier to have them all there by default and delete the ones that need not see the message, rather than to not have a default set of groups and then add the ones that should see the message. It is a matter of number of clicks, and more importantly a matter of the relative reliability/flakiness of the Facebook interface.
One warning, if you choose to use this approach: You should ensure that the default set of groups you set contains all your connections. I have one group which is, essentially, "other". While you could just switch the privacy of a message to "All Friends" very easily, if you use the default set of groups approach for your status update privacy, then only people in at least one of those groups are allowed to post messages to you. (Of course, this tidbit might be useful in the other direction: If you have someone you want to remain a friend, but you want to prevent them from posting to your wall, this is the way to do it. This is different from blocking them from your wall. If you block them, your friends can still see what they posted to your wall, even if you don't. With the default set of groups approach, they get an error trying to post to your wall.)
Rather, if you wouldn't post it on a billboard, don't post it to "Everyone". "Everyone" is just one of the options.
In a broader sense, and going back to what I was saying at the start of this reply, I find that people tend to share too little of their lives with friends as opposed to too much. It was different when we all forged friendships as children and then lived the rest of our lives within five miles of those childhood friends. That's not the way the world is anymore. Facebook is a great way of recapturing some of what we've lost to progress, i.e., what we've lost due to our ability to travel far and wide, and the tendency for us to live our lives much further from where we were born than hundreds of years ago, when many of our society memes were established.
I find a lot of people don't seem to realize that what they post can be found pretty much by ANYONE.
So, just to be sure we have it straight, we can talk about the weather and...well, that's about it....because we might offend someone. Sheesh. I talk about whatever I would like to say on MY PAGE, people can feel free to hide me or unfriend me if they would like. Facebook is a social networking tool, if you don't like the way I use the site, no big deal. But I am not going to change the way I use the site because someone else doesn't like it.
I think this thread is more about when people share a bit to much info , such as their husband is the world's biggest jackoff because he doesn't put his underwear in the hamper or that they had rock and roll sex with 15 strangers on Wed night. People need to realize that they look like complete idiots when posting this type of information.
If folks don't mind looking like fools by all means hop on it and post everything! Some of us will laugh our behinds off and forward crazy status updates to others to get a giggle and others like you suggest, will just delete offending parties.![]()

one minute and
the next!!!People (adults?) really forward status updates??![]()
I think a lot of people simply post TMI updates for the shock value of it. They like to see everyone else's responses is all. I've had to block a few people I am friends with for that very reason....every post is TMI....one minute and
the next!!!
I assume this happens when you don't have your privacy settings set up that only friends can see your status...
Because most people my age and younger who use this site that I know of, they use it to talk about life & what's on their minds at the moment, they aren't really second guessing themselves wondering if people are making fun fo them behind their backs. 
I wonder if it's an age thing, because I am in my 30s and not much phases me...and I see from what my high school friends and my friends post, that we are all a pretty laid back group. Venting about husbands and socks, pregnancy whining, people who can't park, kid drama,etc, we've seen it all. After reading this thread I am thinking that I should make a folder and put anyone over X age in it, and that way when I post anything non-weather related I better hide them.Because most people my age and younger who use this site that I know of, they use it to talk about life & what's on their minds at the moment, they aren't really second guessing themselves wondering if people are making fun fo them behind their backs.

Not necessarily. Say your private with only friends able to see. You put your status as "ABCDEF.." A friend comments on your status. If someone else is friends with your friend, he can see that you commented and can in some cases read your status.
If you are tagged in a photo, you can and will be found through a search engine.
On the internet, there is no such thing as private!

I think age comes into it but apparently not in the way that others do. I've had to hide/delete several OLDER family memebers/friends of family due to outrageous religious and political posts. That's ALL they talked about. Now the younger members of my facebook, not so much.
