Search discovery is by far my biggest pain point, and I say it as a fan.

I disagree with the GGP (I think) about Facebook wanting you to wade throw a river of crap so you stumble on ads. Their ads have been spot on to my interests so far.

I think an onioned version of Google plus circles could help Facebok influence the AI without preventing discovery.

But TBH, had G+ really been a contender at this point? This sounds like the creak of an abandoned house by now.
