SFGate was originally the online version of the SF Chronicle, starting in the 90's. For whatever reason, they wanted a distinct online brand. Now the online version of the Chronicle is hosted at sfchronicle.com and SFGate continues on under the same ownership (Hearst) as its own clickbaity thing. Not much in the way of original reporting.
I know SFGate as the San Fransisco newspaper website that for some reason comes up when you google for questions about repairing old homes. Seems like they're spending their entire SEO budget on lath and plaster repair guides.
