I don’t know how I’ve managed to spend so many years puttering around online without, until today, bumping into Paul Brians’ “Common Errors in English” website. If you’re like me in that respect, and if you’re interested in language usage at all, you should definitely go check it out. Oh, and be sure to take a gander at the “non-errors” page; it’s both enlightening and entertaining.

(EDIT, 19 May 2018 – Nearly a dozen years later, someone emails me out of the blue to apprise me of the link having moved. Helpful!)
