Top 10 Google results for "sex blog" at this moment include:
Two actual sex blogs (me and @girlonthenet)
Two super-plastic marketing/SEO blogs for people selling services like therapy and counseling
Three tube sites
Two ancient pages about sex blogs on Reddit and Quora
One hugely-outdated garbage-compilation blog directory that bait-and-switches to a paid download product for advertisers, when you scroll down.
Google, you're really crushing it!
