I have been having trouble with the crowdflower tasks, I can't get the bookmarklet to work, (I don't even know what a bookmarklet is.) and almost everytime I try to due one of the tasks it says it's wrong. Are these tasks just scams or what? I follow all the directions but I just keep getting all the wrong answers. If anyone could help me figure out to answer them or add this bookmarklet thing maybe that would help.
