Technology author and online information-systems guru Jon Udell says rule #1 for your professional or business information is…
1. Be the authoritative source for your own data
[T]hat means regarding your own website, blog, or online calendar as the authoritative source. More broadly, it means publishing facts about yourself, or your organization, to a place on the web that you control, and that is bound in some way to your identity. Why?
To a large and growing extent, your public identity is what the web knows about your ideas, activities, and relationships. When that knowledge isn’t private, your interests are best served by publishing it to online spaces that you control and use for the purpose.

The great thing about modern website technology (WordPress, Drupal, MovableType, Joomla, and others) is that they all make cross-posting information from your website to different social media (Facebook, LinkedIn, Twitter, Tumblr, Google+, Google Reader, and so on) anywhere from easy to completely automatic.
If you already have a website but it doesn’t connect easily to your other social media I can fix it for you. If you’re already on social media but don’t have a website I’d love to build one for you that keeps you connected while still making you the authoritative source for information about you and your business.
