Hi Ash,
As you've probably seen, we've recently (today) become a CentralNic registrar. Admittedly, we did this because we wanted the .LA and you must go through them to do it, but we picked up their other extensions to offer to our customers.
We're not expecting huge take up of these domains, but from some of the searches I've done, there are a number of good domains that would be great for blogs, URL shortening, traffic blazing, even some brand names.
The .LA extensions has some really good domains that are available too.
