Good to see initiatives like this, grow the hive, I read that the problem then is keeping individuals engaged, some I know from the past expected instant riches and ditched posting after about 6 months as they were not prepared to "work" for want of a better word I kept getting meaasages like " how do I get my money out", told em to fuck off your account is less than $100 keep going...Nope that was the end of one individual FFS.
I guess the only snag I see with promoting hive is that when things are incentivised some will always look to get greedy, and look for ways to maximise their own worth rather than be a team player.
