Like how Burke got in Katie's face about her loooong spelling yesterday. Hopefully she wasn't too offended, but Burke has a real point that would benefit her too.
In my field, lately I've been knee-deep in studies that show online product reviews that are very positive but are written with poor grammar or "creative" spelling typically offer zero lift to the sales of those products -- likely because most readers dismiss the reviewer when they see that. Meanwhile, a critical review with a lot of negatives, written articulately, will actually boost sales of the product -- because many readers suspect there's always a flaw and gain good confidence in knowing what those flaws are from someone who wrote something that sounds credible.
