Have you posted to Turker Nation at all? It might be a good idea to start developing a "brand" for your questions so that you start to have people actively seek you out and prioritize your HITS. As it is, the Amazon search interface lists 1 hit available per website which is getting FeedbackArmied and it might not be obvious to the Turkers that requests for feedback on A, B, C, D, and E are linked so if you had good experience (had an enjoyable task and got paid promptly) on A and C then B, D, and E are right up your alley.
