Pros
You can choose your own schedule and work as little or as much as you want
Cons
You no longer get to choose your topics and often get stuck with stuff that doesn't even make sense, pay per hour has gone down considerably since the new system started despite the fact that they charge clients more, Reviewers hold all the power as to what you get paid and are remarkably inconsistent. Before the new system, you were able to do a question, that you chose both in terms of topic and pay, from start to finish. It was amazing because you learned something every time and made good money (or at least knew what you were signing up for before you started). Now you get randomly assigned bizarre questions that, because you don't know what you're working on, can take hours -- all for $16 to source or $30-32 to complete.
