For some time now, I’ve been using a Greasemonkey script to fix the most prevalent spelling mistakes on the Interwebs. Incorrect apostrophes are particularly painful, particularly prevalent and also particularly cumbersome to fix — the latter two being due to the complexity of the rules governing the use of apostrophes, obviously.
To tackle this, I’ve now adopted brute tactics: I simply replace each instance of
it’s with an
its. So far I must say it has felt less painful to encounter an
its which should have been an
it’s than it is the other way round.
