Facebook, Twitter and LinkedIn Oh MY!

I'm very comfortable using Facebook, but I did delve into my privacy settings and paid attention to what things could be shared about me by my friends' facebook settings.  It was totally beneficial to me to look at those settings and see how I could make sure my information that is 'out there' is locked down to my satisfaction.  For the most part, I see our role with our patrons and facebook to be just being familiar with it and knowing where to go when they are having problems with it.  The question I usually get about facebook is "how do I add my picture to my profile?" 

I had a Twitter account as well, but don't tend to use it as much as my facebook.  I was curious about it so I got an account close to a year ago now.  It's amusing at times and is nice being able to look into the lives of those we admire such as authors, radio personalities, etc..  but for the most part, it's just ok to me.  I can't really see myself using it for helping patrons other than something that is happening in the news 'right now' that hasn't hit the newspapers or the media yet.  Even then however, how reliable can we count it to be?  I'm a bit skeptical about using it as a source for questions.  I think it is however very important to keep yourself in the technological loop so that you are aware of how these sites work just to be able to help people who get stuck using them. 

I do not have a LinkedIn account and am unsure if I will create one.  It would be good to see how it works and such for patrons who want to use it, but I'm not sure I want yet another username/password to keep track of out there in the vast space of the internet.
