Seek or Shout is a new -- so new that it's beta -- service from Cision, a company that helps PR professionals by offering databases of media contacts, media news and other support. According to the site:
Seek or Shout is a new community for anyone who creates or promotes content, including bloggers, journalists, freelance writers, public relations pros, marketers and students.
The idea is that bloggers and other writers can ask the community for sources, ideas, etc. and then promote the finished piece among their peers. Like other social networks, its success will not only depend on how well the site is designed, but whether anyone shows up.
