I still see this over and over on Facebook: profiles used as company accounts. This is an incorrect use of Facebook and of social media in general. A personal profile on Facebook is meant for a person. No one wants to engage with a Facebook user that has a company name as the profile name and company logo as a profile picture. It is impersonal and uninteresting. Your Facebook profile should be you, with your actual photo (not a picture of a tree or something) and not your company logo. People want to interact with other people.
Facebook fan pages are the best way to create a business presence on Facebook. That is what they are designed for. Use your company fan page to create your company presence on Facebook and then invite people in your company to contribute to it.
Profiles are for people; fan pages are for business.
