The editor is to be congratulated on his selection of articles. As such, this free newsletter gets a thumbs up for the work so far. If only others were so selective. I've gone on before about the importance of personality to an e-publication. The decision to unsubscribe is no longer just about dropping a newsletter, it's also about cutting a relationship with a person, however tenuous that relationship may be.
Personality encourages loyalty.
But maybe it's time to also sing the praises of an editor for the job of editing. Mollie, for example, has the unenviable task of turning my British English into something more acceptable. If you're a one-person operation, you may not be able to afford to hire a professional editor like Mollie. But a proofread from a friend, partner or relative will also pick up errors you missed yourself, not to mention produce handy comments on style and content. So if you get the chance, get a second opinion.
