I just want to share an unusual thing:
I am doing a daily import of the alexa and quantcast top million site list. Just to see some global trends on populair domain names.
Today i noticed 387,000 new domains in the quantcast list where normally there are less then 100. The first new site has a ranking near the 1000.
There are also almost 310,000 updates in the quantcast list for existing domain names.
Conclusion: 39% new domain names and 31% updates in the quantcast top million list today.
