A lot of researchers (including a past version of me) get really upset when someone else beats them to the punch with a project, but the more intermediate researcher I am today revels in it. If someone else has produced useful findings, why not use that to do a follow-up study to test their findings? There are always new opportunities for research, especially in fields related to writing or communication, which is constantly evolving.
So, here is a report based on a survey of 247 freelance writers on the state of freelancing today: The-State-of-Freelance-Writing-2014.pdf
It’s by http://www.copypress.com/, which is one of the good guys, at least from my initial research into this area.
