Just yesterday, we were hearing gossip about how Condé Nast, the magazine publisher, had spared Wired while slashing Portfolio, its troubled business magazine. Not so: Wired.com is having layoffs due to "unexpected cutbacks," Silicon Alley Insider reports. No details on numbers yet; the publication is having a conference call to discuss the cuts now. Wired.com, which is managed separately from the magazine, had gone on an acquisition spree of late, having bought Reddit, Ars Technica, and Webmonkey recently. It also had plans to resuscitate HotWired, a '90s-era Web property which popularized the banner ad; those may now be on hold. Update: More details have arrived on the cuts. A quarter of the 50 or so staff in Wired.com's San Francisco newsroom are gone.
