Do you participate in a social-network reading group? Here are ten of the myriad virtual reading tribes populating the web today. I’ve looked into some of these and even have a profile on Goodreads, but for me, nothing beats my live, once-a-month outing with good friends to talk about the stories we’re reading. It happens that we are all professional editors and writers, so a passion for reading runs deep, as does our friendship. It’s difficult for me to imagine replicating that online, but perhaps it’s possible. Tell me what makes book-based social-network groups work (or not) for you.
