It's not worth getting excited about. Surveys are too infrequent, and don't reward much. My last one gave 6p. in almost 7 years I've made £84 (Roughly £1 per month)..... This is poor. If Google want people to use this they should reward more or offer more surveys, it isn't costing them, and recipients will spend their rewards here. Considering that millions of people will download apps via torrent sites or apps like 4shared or Blackmart for free, Google really need to up their game here
