Thank you. Although I prefer “I now present you, Exapno Mapcase, with this $100,000,000 check.”
The British don’t say otherwise. Isn’t there the same split between prescriptivists and descriptivists there? No modern linguistics expert has been anything other than a descriptivist for at least 75 years, BTW, in Britain or the U.S.
And of course I said absolutely nothing remotely resembling giving a pop-writer-du-jour authority. That would be as idiotic as giving some self-styled style expert authority. I say English is similar to science. The consensus of the pool of experts is what counts, not individuals. You dont’ read no good.

“Capitalize the first word after a colon only if it is proper noun or the start of a complete sentence.”
Writers’ Hotline Handbook
“If what follows the colon is merely a list, do not capitalize the first word following the colon unless the first word is a word that would ordinally be capitalized…Otherwise, capitalizing the first word is optional.”
Webster’s Secretarial Handbook doesn’t state a rule, but the examples it shows follow the proper noun-only guideline.
