MySpacers, Facebookers, etc.; put thy social networking skills to use for your career. If you're unawares, social networking refers to any web-based networking system. Although the aforementioned social networking giants are well known, there is a growing metaverse of social sites that focus on specific interests, hobbies and careers. (Indeed some industrious Columbia students have started one specific to our school.)
MyCreativeCommunity is one such site which focuses on screenwriting and screenwriters. It's new, so it's not yet what one would describe as "jumpin' off," but it's getting there with the help of a little media buzz.
Non-screenwriters, take heart. If a social networking site relevant to your career isn't out there, you can get one started. Networking is after all a part of the portfolio process. What good is great work unless you have people (other than your roommate and mom) to show it to.
