When I spoke at the first-ever Financial Blogger Conference I noted the sin of “comma splicing” (among others). A couple of people approached me later to say they were guilty of committing a crime they didn’t know existed.

Comma splicing is the act of using a comma to join two independent clauses. Here’s an example* I saw recently: “Initially it appeared that things would be fine, the shop accepted my coupon and assured me the work would soon be completed.”
As the “Archer” character Lana would say: Noooooope!
