Social networking (facebook, twitter, linkedin, etc) have become an important part of having a web presence.  They provide additional outlets to allow people to see your site as well as broadcast messages in mass to people who are interested.  If you have a website it is probably worth setting up a a few of the social networks to link to it.  However, if you don’t commit some time to the sites, it will be a waste of effort and may backfire because people will lose interest.

Get involved in your online social community!  Happy Networking!
