Grammar Girl

My favorite recent addition to my podcast subscriptions is Grammar Girl's Quick and Dirty Tips for Better Writing. (http://grammar.qdnow.com/)

The young host (no name, just Grammar Girl) offers short episodes that clarify confusing grammatical issues, from the proper use of "affect" vs. "effect" to the proper use of quotes. The episodes are not exhaustive treatises, though she often expands at the site itself ("effect" as a noun is mostly true, but there are verb uses, just as there are noun uses of "affect"). But five minutes every week to clarify or enforce some common mistake? Even I can fit that into my schedule.
