Any sort of content written by or associated with Internet linguist Gretchen McCulloch. Gretchen McContent includes her blog, All Things Linguistic; her podcast, Lingthusiasm; Crash Course Linguistics, which she writes for; Tom Scott's Language Files, which she also writes for; and every other linguistics resource on the internet, which she also writes for.
I used to only listen to Lingthusiasm, but now that I discovered All Things Lingustic, there's so much more Gretchen McContent?
