No, no, no. ToysRUs made a perfectly logical decison that most any business would do and Google tanked them for it. ToysRUs wanted the url to direct to their site.  They're all about toys and they simply bought a url that described their business and told the url where to take people.  Google tanked them in the rankings because came with link juice. Google assumed that was doing this to manipulate the search engines but there is just, to my knowledge, ZERO evidence of this.  This is another case of Google caring more about the possible spam threat than the actual rankings for searchers.
The easiest way to see that is to go to HREFs and look at the anchor text. It reveals right away whether or not the site has been spammed. You also want to see if it’s been SEO’d too much. Right? In this case, it’s not because it has a brand name here and some natural keywords, but if the number one anchor text was like, cell phone management system and then the next one was like cheap cell phone management system, you’d know that the anchor text was manipulated and probably overly SEO’d. So, what you want as a site that has a natural link profile.
"Expired Domains" will help you grab and search through all those domains that are expiring in a organized matter. You will be amazed how many good domains are expiring every day. With Expired Domains you should be able to find a domain you are looking for. It may take some time, and you should not expect to grab something like Sometimes you will also need to use a backorder service to assure (as much as possible) that someone who aimed at the same domain as you doesn't grab it before you does.
At the end of the day, this article is geared to startups, business entrepreneurs, webmasters and marketing professionals who need to understand the process, and I guestimate that the process listed in the article above accounts for 99%+ of all expired domain names. All of your points are valid and appreciated, but if someone is interested in buying a good, brandable domain name for their business, they should follow the instructions above to have the best chance of grabbing it.

I registered for backordering with GoDaddy last year, as i saw goddady was the registar of the domain i wanted. However when the deadline for renewal came, i got a message the expiration date had changed to expire… well, a year later, i.e. now in 4 days. How can the expiration date be postponed? Was that the registrant renewed? does that mean the domain never becomes available and never goes to auction?
If you buy keyword specific domains, you're really buying the type in traffic.  I use the URL builder and redirect through that URL so you can see how much traffic your getting from the keyword domain.  There seems to be no rythme or reason to what keyword domains deliver traffic and what don't.  By tracking traffic with the Google URL builder you get a feel for what names are giving you traffic and which are not. ie. the plural, the singular, two words, three words, the possessive, etc.
We do not only have Expired Domains, but you can also find lists of Deleted Domains for a lot of TLDs. Deleted Domains or Dropped Domains are available for registration and can be picked up for just the normal regfee at your preferred domain registrar! All Domains have the typical SEO relevant data, like Number of Backlinks, Birth Date and a lot more.
