I was checking #darkcoin in twitter and seems to me there is a big diverse group who are aware and are just waiting for good things to happen here organically.
I totally agree with your observation.
I think it's a matter of risk - and for most people, even for early adopters, this is still an unproven beta.
I expect that will change within a ~month when Darksend becomes official and its source-code opened. There will be a lot of steering around it then.
