Domain names are a great way to remember and navigate to websites of interest. Even this blog has a domain name:http://barronblog.com.
Recently, I started a twitter account and the tweets go both to my Facebook page and my Blog page. My Facebook page also has family and vacation pictures that I've taken. To make it easier for visitors, friends and family to access my Facebook Homepage, I've created a new Domain Address:davebarron.info. Tweets, facebook entries, pictures, and wall comments by friends and family are found there.
You can use other domain addresses to gain access to my websites at Hotel California(www.log-line.com), Gehenna(www.hellfun.info) and Katimavik(www.katimavik.info).
I used Godaddy.com to register my domain addresses because they are cheap and efficient.
