I too am a bit confused with the blog thing here. I suppose it is a new thing that needs some refinement before the blogs become really useful. I see them as a way to post more permenant stuff, or at least most blogs seem to work that way, unlike the forums where posts disappear into the lower eschelons of forumness many times before people see them.
I too am on Linked-In. As Derrick says, Linked-In is for necessity. I have to admit with LI, I have been able to maintain contact with old coworkers that were laid off years ago, and I've even found people to hire as my assistants in my current job.
Facebook happened a couple of years ago for me because I support the piano collection I speak of often here. A group was setup for the Frederick Collection
www.frederickcollection.org and one of my real friends got me hooked on there. I posted their current concert up on the group so others can see it. (Advantage for Facebook). For years I didn't do anything with Facebook, then some other real friends joined. My storm chasing friend, Roger Hill,
www.stormchase.net, now posts all his current and not-so-current photos up there, so I go there now to see his pictures. My other storm chasing friends from Silverlining Tours are up there as well, along with other top-notch chasers and meteorologists who also post some of the most gorgeous photos I've ever seen. Recently the guy that built my clavichord joined and saw my instrument. (Remember that link I posted about being famous?) I also met one of my distant cousins. She happens to be a friend of one of my storm chasing friends in real life, and also knows a piano world member I know in person. Talk about a small world!
So what started as a link to the Frederick Collection group has become a small community for me, not unlike the forums here. What is nice about Facebook is it is unmoderated, so if you want to talk politics, about, storms, trains, and music, pretty girls, or whatever, you can. There's no one to stop you.
Now keep in mind, there are certain rules you need to follow. These aren't written rules, but consider them common sense rules. I post there only what I want known in public. By doing this, I have my personal life which I don't say anything about there. You guys know more about me personally than nearly anyone except for longtime real friends up there. The reason why I do that is because current and future employers do check Facebook to see what you say and think before they promote you and hire you. So you really have to be careful. I also post respectfully the way I want people to treat me.
My dumb sister posted a numb nut post about her manager. She got fired the next day. D'oh I wonder why! Oh we could contend it was public, free speech, etc, but there are places to say certain things, and places where not to say them. This is public, alright and to me is no different than the park or town high street! In real life, if her boss heard her say this at the mall, she could have been fired just the same.
There are also posts up there by other people I know that I distance myself from. The vulgar language that flies out of their posts even make my ears turn red! I'm not so innocent when it comes to those unspoken words here, but again there's a time and a place to say them (like being cut off on the highway by an idiot using a cell phone!). People forget what's placed on the net, especially on places like forums and Facebook, which is nothing more than a giant blog/forum, is there to stay for decades.
So Facebook maybe something to consider, just use it to your advantage. Their picture libraries are awesome. I have to admit I don't care if I'm liked, or unliked. (Why is there no dislike button?) I'm not 12 years old, though many people act that way up there. This is the sad childish side of things, which seems to be the case with lots of things today. Sap it up, dumb it down, make it easier, so the people will "like it".
