What do you like best?
MTurk Crowd is a great resource because it allows you to ask questions about mturk, learn more information, find great HITs and also just chat about being a "freelancer". I've learned a lot about scripts, the ins and outs of using mturk, and about which projects I should accept and which I shouldn't. Everyone has been very understanding, reasonable and the Mods are great!
What do you dislike?
Not a lot of people use it as a resource. There are so many people using mturk and not speaking because they're "competition". I wish more people used it in order to gain more insight into the forum and also help people out.
Recommendations to others considering the product
Consider that not many people use mturk crowd because they aren't aware of it. A lot of the information that is found there, can be found on Reddit but the insights from others and the scripts are of high quality. I highly recommend using this product to help flesh out your financial needs. Not technically for businesses unless you're want to use it for surveying purposes. If you are using it for surveying purposes, please do as many HITs as possible and for a good chunk of change ($0.50 or up). I also advise that sometimes you will be rejected for turks but that's okay! Just move on and try to do better in the future for those types of projects.
I definitely think you should use this resource as it is something worth using to learn and get around the mturk site.
What business problems are you solving with the product? What benefits have you realized?
