Add "Domain Tasting" to your list of technology buzzwords.  Domain Tasting refers to the practice facilitated by ICANN's contract with its registrars that allows  a 5 day grace period during which any registrant can delete a newly registered domain and get a full refund.  The grace period was designed to allow for the correction of typos and spelling errors.  However, it is now being abused by domain speculators ("domainers", if you want to add yet another buzzword to your lexicon), who use automated software to register domains by the busload, slap up web pages full of pay-per-click (PPC)  ads, and then only keep the few that make money during the five day test period.

As a result of this, any name that is on a pace to make more than $6.00 a year through PPC ads, will end up ultimately being tested and held by a domainer, and not available for more legitimate commercial use.  Inevitably the names that are kept are typos of popular names, and expiring names that are already registered with the search engines, and thus have some traffic.

Whether ICANN or the registrars take any action remains to be seen.  In fact, speculation is that the registrars are actually some of the main culprits in domain tasting for their own accounts.  At least one lawsuit has been filed targeting the practice.
