it's not just about how many hits, it's about what type and variety of hits. If you do searches, you have to have a high number and work for different requesters, I think.
GREAT! Now Andy K is also requiring the Masters qualification???? This is really becoming obscene!!!!
Ive had masters in the past 2or 3 time, and have talked about it via email with people from mturk. They take a random sampling of random workers work when they need masters and assign them at random. Then later they can always pull them away later do to work load.
