i very much see it happening, but some patience and perspective is called for.
We should consider all the positives over a relatively short period. Look at GoldCoin's value at the beginning of November, less than 8 weeks ago; it's done very well since then. The forum membership has increased in parallel and there are a now GLD specific utilities emerging (marketplace/localgoldcoins) and of course the official video project, all of which provide a platform for growth - but it's not going to happen overnight.
As for who's doing anything, i suspect there's a lot of activity but not all shared publicly on the boards. For my part, I've made a number of donations where obvious effort has been expended by community members to further the cause (which we could all do, cause it all adds up!) and I've encouraged friends to invest c$2k in GLD (all with 'talk' i hasten to add!). OK, not earth shattering i know, but i doubt i'm the only one extolling the virtues of GLD in a predominantly 'off-line' fashion.
