Streamline Social NetworkingSocial networking can be a useful business tool, but you can also spend enormous amounts of time sifting through messages from irrelevant people and companies. Consider a service such as Ning or SocialGO, both of which let you create and control your own private social network. Bonus: Admittance can give clients and business partners the impression of white-glove service.
Archive Your E-mailDon't want to spend hours every month deleting old e-mails and worrying that you may have discarded some you might need later on? Consider a product or hosted service that compresses and archives messages, rather than forcing each computer to handle that task. Fewer old e-mails on your computer means there's less chance that Outlook or Entourage will crash, forcing you to retype messages or restore its database.
Hosted services include everyone.net's one_archive and LiveOffice; these often are bundled with other services, such as a hosted Microsoft Exchange server. If you prefer to own the hardware, one place to start is Exchange's archiving features.
