I have a bit of an hard time articulating what I mean (ESL), but what I mean is that these days depending on what profile companies have on you (your assumed interests, income, education etc), your experience on the internet, apps will differ more and more. In order to improve retention and engagement, they will try to tailor the experience and give you what they think you want instead of letting you get it yourself, effectively creating a bubble around you.

In the context of my comment (internet dating company), it means even when you try to meet new people, we will make broad assumptions and present you people we think will match well with your assumed race, income, education. All for upping that retention a few .1%

In earlier internet, the experience on a single website, for example, was the same for everybody, no matter your demographic. I understand why it evolved, but I regret it a bit.
