There are tons of blogposts out there about social media and how to act on social media and this is just my opinion. When you first sign up for Facebook, Twitter, a blog, a website, etc. you immediately start leaving a footprint.
Did you know every single tweet is saved in the Library of Congress? Of course, "only tweets from public Twitter feeds will be included, not those that have been set as private." Read about it here: http://bit.ly/c4TLGC
When you start looking for a job, whether it is on social media or not, the first place a future employer starts looking for information about you is the internet. They look through your Facebook, Twitter, website, etc. In one of my first interviews, my interviewer told me he had been following me for a while on Twitter and had been looking through my tweets, I had no idea.
Of course, that didn't really bother me because I keep my tweets pretty professional with a little bit of personality and my personal interests mixed in. I never really had anything terrible on my Facebook, but I've cleaned that up too and added my professional sites to it as well.
What is an employer going to see when they look at your page? If you are tweeting offensive things, things like "I ate a grilled cheese today," misleading things, tons of profanity, tweets that bash people, etc. you are not going to look good to an employer.
Another tip: don't tweet about hating social media or bashing social media if you are on any social media site because that's pretty contradictory and someone might wonder why you're on any social media site to begin with.
On Twitter, try to engage companies, other people and different Twitter chats in conversation so you are tweeting professionally and with other people. Get involved in your interests and your career, no matter what it is. Here is a link to my favorite Twitter chats: http://bit.ly/g7Q3Xf and a link to all the documented Twitter chats: http://bit.ly/b2jErT.
I would also recommend watching what you post as status updates on LinkedIn, since it is a professional networking site.
Employers are out there looking. Do you really want something online that you post to jeopardize anything for your future? Think it over.
What kind of social media footprint are you leaving? What do you want to be known for?
