At any one time, there's 1-3 of them in Portland, Oregon. The one that's lasted the longest, xmag.com, has a publisher that owns half a dozen venues in town, some of them strip clubs. The content is mostly ads for clubs, escort services, and seasonal promotions for contests to draw people into clubs during the dead period/dry season- bar receipts at "adult entertainment" venues crash hard in the NW when the sun's out every day from 5 AM to 10 PM. There are also regular columns from people working in the publisher's venues, usually related to strip club topics like "My Job as a DJ sucks", "My experiences as a sugar baby", or "Don't wear chain mail underwear and expect me to give you a lap dance". Most of the columnists move on after a few years, usually after they decide to stop working in the local strip club scene.
