If so, you should read this, print it out and stick it on the side of your computer monitor. Then re-read it every time you sit down to write a post discussing actual scientific research.
What if you want to write for a scientific audience ? Blogs are not only useful for science dissemination.
Sure, that is a different style altogether.
But most of us (at least at this point in the history of blogging) write mainly for the lay audience. Or for scientists in different fields who would not otherwise be able to understand the actual papers - we bring in the history and context to explain why the presented work matters.
I posted a comment over at Cognitive Daily. Dave's description is way too long to post on the side of my monitor. If you want the short version, according to me, it's "get the science right" or,
ACCURACY, ACCURACY, ACCURACY
Ha! Of course. Without it all else is superflous. But once you get Accuracy right, Dave's advice is golden.
