If practically no one knew they existed, I couldn't do that. It's fair to say alot of people don't know they exist but the people who do like them, they are affordable and brandable and that's what any alternative extension should be. .net is far more expensive and I'm not convinced the type ins, brandability, or wow factor justify the extra cost. They have ageing and mindset on their side, I'll give them that, but if I wanted that I'd go for a longer tail generic or brandable .com.
