ok, all the names posted have an overture score. The US overture tool can be found here
http://inventory.overture.com/d/searchinventory/suggestion/
An overture score is an indication of how many times that actual domain was typed into the Yahoo (or one of the yahoo properties) search bar, rather than someone typing into their browser bar, for US searches, overture returns results >25, meaning it had to have been typed in at least 25 times to have an OV score.
The donation is 10X the OV score in DNF$, therefore a score of 25 carries a mandatory donation of 250DNF$. DNF$ are availble by making posts, from the DNForum bank or for sale in this thread.

The trick is to sort through the list and identify which domains are worth registering. It all depends on your goals, do you want traffic on a certain topic, for instance are you only looking for sports typo's? Do you want to park the domain and collect income from parking services? Do you want to develop the domain into a site? Earn PPC or affiliate income? Does the name have potential on it's own for resale later on?
How do you decide if the name has value? Lots of things fall into this category, and most are subjective, but there are a few tools we all use, like archive .org to see if the site was ever developed before
http://web.archive.org and a yahoo search like this linkdomain:
www.exampledomain.com will tell you how many links still exist to any site that was already developed.
If it is income you are looking for, it's not a get rich quick scheme, but a way to build an inexpensive revenue generating portfolio. Are you looking to make $$$$ or are you happy with a 3 cents or more a day per domain, which, by they way is an excellent return on investment.
The thing is....I justr haven't seen anything interesting in the last few months. Seems to all be expired names these days.
