Prescriptive grammarians may enjoy this, even if it destabilizes their strict sense of right and wrong: Slate has detailed the 250-year-long grammatical quibble over the correct use of “hopefully,” that ever-present eye twitch of incorrect adverbial usage.

If your eyes aren’t tearing up with that twitch yet, take a look at io9′s ambitious compilation of the most disastrous typos in Western history.
Meanwhile, in the same spirit of chronological grammar-mapping, The Atlantic has compiled a web app history of the New York Times’ stiff slang explanations (example: “Diss, or a perceived act of disrespect”). And the game-side disputes can finally end: Scrabble has added over five thousand new terms to its updated player dictionary, including such witticisms as “sudoku” (shouldn’t that be a proper noun?), “buzzkill,” and “vlog.”
