We recently held a Social Media training class, and this question came up and was discussed pretty strenuously: what SHOULDN'T you do on Social Media? Interestingly enough, this question was related to what you shouldn't do on your personal page, not your business one. Many people have work friends on their personal Social Media platforms, so there are moments for awkward interactions. Here's some things you should absolutely avoid:
1. Whining: Seriously, don't whine about how hard your life is and don't complain about others. Especially don't make passive aggressive comments that are clearly directed at someone specific but that you don't actually say to their face. Facebook is not a platform to become twelve again, and complaining about people gives off a really awful impression.
2. Politics & religion: If you are active in the business world, try to steer clear of political conversations on Social Media. You never know who you are going to offend, and remember, once you put something in the digital world, it is out there for the whole world to see.
3. Self-aggrandizing...too much: Everyone self-promotes a little, but if you do it too often, you turn people off. Make sure you are walking that fine line of letting your network know about your accomplishments and stroking your own ego.
4. Violate your company's Social Media policy: Make sure that, however you use Social Media, your use conforms with your company's Social Media policy. Not doing so can put you in a position where you can get disciplined or fired. Don't know your employee's policy? Find out what it is.
5. Overextend: Have a Facebook, Twitter/YouTube, Blog, LinkedIn, Quora, etc? Great! But can you actively manage them all? No? Then cut it down. Don't let a profile lie fallow...your network will not be pleased.
