Vocab we all need

I am reminded that the word "frobnicate" should be more widely known.
http://catb.org/jargon/html/F/frobnicate.html
"Usage: frob, twiddle, and tweak sometimes connote points along a continuum. ‘Frob’ connotes aimless manipulation; twiddle connotes gross manipulation, often a coarse search for a proper setting; tweak connotes fine-tuning. If someone is turning a knob on an oscilloscope, then if he's carefully adjusting it, he is probably tweaking it; if he is just turning it but looking at the screen, he is probably twiddling it; but if he's just doing it because turning a knob is fun, he's frobbing it"

Online spelling quizzes

Two have popped up lately, both IMO quite tough.
The BBC:

and the Guardian (after the score I got, I won't throw any stones)

20/20 and 17/20

"Pretty good. You're clearly someone who appreciates the language of Shakspear" says the Guardian - note spelling of that final word!
