(Some) Models Have Pages...
Sharing public model pages & some of your best pictures to network with other industry professionals is part of a model's self-promotion.
Keep your personal friends page seperate from your professional model page to support your privacy vs. career! Although the amount of fans helps increase the reach to other people, "quality" supporters on your professional page are
more important than just the "quantity".
On your page's photos, give credit to the people you work with at photo shoots such as photographers, make up artists, stylists, designers, etc...and mention your representation ;) if you are with an agency. Check if there are any special specific agency rules or tips about social networking.
Try to name albums based upon content or type of pictures inside such as Fashion, Runway, Commercial, Beauty, Tear Sheets, Catalog, Promotions, Bikini, Lingerie, Art, Fitness, Parts Modeling, Glamour, Just "Testing", Backstage, Miscellaneous Fun, etc...think of them as individual portfolios.
Less is better. Don't over-saturate your albums with too many pictures. Put appropriate pictures that belong on a model's page.
