I use and really appreciate facebook for my business. For me, my business is all about making friends with clients, keeping them as friends, and expanding on those friends for more work. I post pics of what I do, and share them of jobs that I'm working on.
I've found that the more I share, the more interest I get, and the more calls I get about doing something for a potential client.
Getting my name out there is always the biggest challenge of any business. Keeping it out there and being the person that everyone is thinking of is the next biggest challenge. Facebook allows me to do this on a daily basis.
The more friends you have, the more people that you have who might hire you, or tell somebody else about you!!!!!
