The job is not hard: once a week, recommend a story or stories to Giles readers. All the fun is in how you do it. Maybe you cover a broad range of Giles fandom, or maybe you dig deep with an expert view into one aspect of Giles fandom. Sell the stories to the readers! I often write summaries that are completely different from the ones the authors wrote, because I'm trying to coax a slightly different audience into trying it.
The task is as much or as little work as you want it to be. I've spent hours building themed rec lists some weeks, and other weeks spent five minutes writing up a little blurb for a single story I loved a lot. It's also not a long-term commitment. Recommend stories until you run out of suggestions, then step aside and enjoy somebody else's taste for a while.
Rules are very simple: never recommend yourself, mark adult stories as adult.
