why don't they just join DRK instead... not need another coin

never heard of shadowcoin before
The proposal merges the two coins and they'll keep whatever stake they had, but in Darkcoin instead. It's the first "coin-merge" to ever happen in crypto.
I've had a chance to think about the merger, I'm a little disappointed it didn't go ahead.
To me it's obvious Instant(tx) is going to mean Darkcoin can one day become an enterprise grade financial platform, for this to happen it's going to take a small army. Evan needs help and I'm will to guess we all let him down a little today.
I honestly think there are enough great devs in the world that we don't need this path. Look at what this thread turned into with screenshots of really crappy conversations, fudwar fuel etc.
Active recruitment and foundation membership (to be released soon apparently) will be a better path. Onwards and upwards.
