First, Lars (of Steno Diary fame) has updated Erika's PloverLearn modules to include analytics, plus drills for common briefs! Check 'em out at HaxePloverLearn.
Second, Charles has produced another homemade steno keyboard that's even snappier-looking than the last one:
He also includes an illustrated assembly walkthrough with a bill of materials, which comes out to about $120 in total. Pretty dang slick!
And finally, Stan Sakai, the ever-glorious Plover Poster Boy, has produced a brilliant little three-minute captioned whiteboard video explaining the rudiments of steno:
I'm in awe not just of his artistic skills (he actually drew the Plover bird!!!), but of his power to break down complex concepts into simple examples that nearly anyone can grasp. Seriously a tour de force.
