I recommend you consider all your online activity as essentially a strategic marketing initiative. Take care about sharing personal information on family and friends you wouldn’t want Hannibal Lecter to know (a bit dramatic maybe, but accurate). Take time to carefully consider precisely what you want to communicate. Write it down, review it a few times, then think about how you will communicate it. Will you blog daily, weekly, monthly? Will you setup and post to a Facebook page? Will you setup a LinkedIn profile? Will you Tweet some aspects of your life on Twitter? Whatever you choose, take the time to be strategic about it.
