Yesterday Google+ launched several new features (including availability for Google Apps users), including What's Hot, links to popular public posts on the site. After months of continuous improvement, this was Google's first miss-step with +.
The mistake is putting unrelated items in the middle of the activity stream rather than in the sidebar or black menu bar. I don't want the students I am trying to use Google+ with spammed with pictures of Britney Spears and bloodstained women hitting a cliff!
As of this morning, What's Snot has disappeared from the Stream, but it's not clear if this is a technical issue or a rethink. Maybe Google had the WTF were we thinking? revelation. Google learned nothing from the pain of Buzz - if you're going to introduce an intrusive service, make it opt-in, not opt-out.
I can understand where this is going, advertising is on the horizon. I don't have a problem with advertising on free services, but this is just spam. Please send feedback to Google+asking them to fix this error. While you're at it, +Vic Gundotra and tell him what you think of What's Snot.
