Last week’s column contained an error. The writer of the Piedmont Review of Food (piedmontreview.blogspot.com), a Carrboro food blog, is not Paul Jones. It’s Jacob Kramer-Duffield, who is a Ph.D. candidate in the UNC School of Information and Library Science. I apologize to both men.

Kramer-Duffield’s research focus is online identity. “I began a food blog because, well, I spend a lot of time onlineit’s what I studyand I spend a lot of time making, eating and thinking about food,” he says. “So using a blog to catalog the recipes I use and create, the beers I drink, the restaurants I go toso that I could actually remember what I liked and didn’t, and how things turned outwas a natural step. I’m glad when other people appreciate what I’ve written, but it’s also just nice to have a written record for myself.”

The Diner (410 Glenwood Ave., Raleigh, 835-9010, www.TheDinerRaleigh.com) is now open on Glenwood South. The Diner serves up sandwiches, salads, burgers and entrees, plus breakfast anytime, including eggs benedict, omelets, French toast and a breakfast burrito. Oh, and shakes, sundaes and malts, such as the Fluffernutter, with vanilla ice cream, marshmallow fluff and peanut butter fudge; and the Knickerbocker Glory, with vanilla ice cream, fresh berries, raspberry sauce, crushed Nilla wafers and whipped cream. The Diner is open 24 hours, seven days a week.

This month, Whole Foods Market‘s Durham store (621 Broad St., 286-2290, www.wholefoodsmarket.com/stores/durham/index.php) is offering free classes on selecting and preparing fish. Called “School of Fish,” the series is from 4 to 6 p.m. on Thursdays.
