I just noticed a new entry on domaintools- It is a link called about us: "wiki article on mysite.com". The link goes to a site http://www.aboutus.org, "The free directory about every domain in the world that anyone can edit" This site lists pertinent info about the site such as description, lang, address, and contact info. Not every site I looked at in domaintools has this wiki link (I'm assuming you must have all the contact info available on your site first), but the interesting thing is that I also picked up about 30 extra listings on this site as they put me in most every category for which I have a meta keyword, such as keyword, keyword, city, city, city, etc. Pretty nice! Here is a sample domain for you to check, note the categories on the bottom. Check to see if your domain info is listed, if not you can update it. http://whois.domaintools.com/microsoft.com
