I'm happy to support anything which gets more good people onto Hive in a cost-effective way.
I've got a thought on the metrics;
Is there a way to measure (while still protecting and respecting privacy) the number of people this marketing effort adds to Hive who are still active a month later ? This could be a really good metric to understand the cost-effectiveness of the campaign, by giving us a figure for what it costs to add each active user.
