Ask HN: Added someone on Facebook/got suggestion on Linkedin

1 points3nnyy3 comments

I just added someone I met on Facebook. Now this person is suggested to me in search on Linkedin. Is it rapportive or some other browser extension doing shenanigans or how does this happen?

I know Microsoft is involved in both Linkedin and Facebook; so there might be also a connection there?

Maybe that person looked you up on LinkedIn.

The key is that the other person's behavior is viral in terms of forming connections between the social graphs. It is why Facebook and Linkedin and Google all want my contacts...and locations.

Match.com has a commercial where they show a feature which displays romantic candidates based on how many times two unacquainted people were nearby.

She does not have a Linkedin
