There are a lot of complaints over the past few years about how startup sites are going with strange domain names: taking out vowels, coming up with original domain names.
In order to be memorable, there are two ways to approach getting a domain name: be original (e.g. 'strange') a la 'meebo', or have a common word or phrase. All the common dictionary words are gone, as are many common phrases. And where have they gone to? Domain squatters, mostly.
