Mindviewers is really nice and well-rounded platform.
It borders around advertisment and social interaction and I must say, it's a really nice initiative.
Advertisers can post paid tasks, but only after attaining a level of reputation, this helps prevent scammers from cheating honest People and refusing to pay them.
For the average user, it helps us interact, build our trust graph/circle and make money doing it.
Reputation helps ensure that active users get rewarded for their time spent on the platform.
What are you waiting for? Hop in already and start earning those bucks the @mindviewers
