On a mobile ?!

> filling out surveys

Selling my privacy you mean ? I guess this will be your biggest source of revenues. People do not seem to mind to sell theirs for a few dimes. But not something I will do easily.

> writing descriptions for online shops

So this would be like 'Do you own one of these machines ?' and then I can pick one and write 'Best dishwasher ever !' to earn an easy dollar ? If so, this is getting morally offensive.

You're assuming the worst on all of these things. http://en.wikipedia.org/wiki/Occam's_razor

Filling out surveys = providing your opinion. Could be completely anonymous.

Writing descriptions for online shops = writing product descriptions for shops who add a lot of inventory but need human-written and unique descriptions.
