more daily surveys to get qualified by for credit.. I know getting qualified can be a pain in the butt but it seems the easiest for me. Or they could use more of the "click on 4 of these and a sponsor add and redeem credit" which is pretty easy and simple.
I think there should be fewer daily surveys that would be considered "good quality" surveys that pay higher (and therefore harder to do, but not necesarily longer.)
I'd prefer this over a whole bunch of surveys that are "cheap," meaning the technical 'infrastructure' of how they are created, who they are targeted for and also how they are processed in the qualification, tracking and crediting system, because sometimes one can spend a very very long time on them for nothing, whether or not they "successfuly" qualify and complete them.
