Need advice

Can push notifications become a good alternative to Facebook?

First of all, https://dontasktoask.com/ and https://xyproblem.info/

Secondly, depends on what you market. For some facebook is a goldmine, others use push and hate on facebook.

When Facebook bans everything in sight, any source will look like a good alternative. But seriously, during Facebook's recent storm I tested the Richads network, got good results, comparable to Facebook. I managed to turn a nice profit here
