Don't want to beat a dead horse but...
TLDs like .coop or .museum have been around for a few years. I can't remember stumbling on a single site that use one of these TLDs *yet*.
I guess it says something about what they stand for... pointless TLDs.
Just because you create a new TLD doesn't mean demand will follow or that it will be readily accepted, even with all the advertising and hype.
That being said, I do hope a lot of domain speculators will rush in to grab .mobi names so I will have less competition when hunting .com names
