This is an answer I gave a friend asking how do we develop and propagate "meaning 3.0" (or the meaning crisis).
To develop and propagate the new approach to meaning means you have to first assess where it is most used and where it is most sourced from. The easy answer to that is religion, which of course is fraught with all sorts of bugs in the code, but there are solutions here.
You expand religion to include non-religious beliefs. This can be approached in a few ways. 1. Assert that all beliefs are religious. To believe, it can be said, is to "know" without empirical support. So this is kind of a technical appeal to the assertion. 2. The practical appeal - "non-religious" beliefs operate the same as religious ones anyway. I used to know of a purple lady in my city. Her clothes were purple, jewelry, even hair. And I heard that her house and belongings were purple as well. One would say she wore purple religiously. It truly was a belief system for her. It represented royalty, magic, passion, and beauty. She lived her whole life in accordance with a color.
That's just one extreme example of what we all do. We all operate on a system of religious and non-religious beliefs.
Since around the 80's religious belief in the US has declined every single year. And yet not all these people are turning Atheist. They are vastly turning "spiritual but not religious". That is to say, having a belief system, but not with organized religion. They are still religious, just not THAT kind.
The era of Open Source Religion happened decades ago but the people participating are quite disparate from one another, mostly because we have not found the proper platform or banner to rally under, which I think is kind of where your original question comes from.
More on the subject though, by designing a new and open "religion" you provide a space for the myriad of disparate belief systems to find common ground in, at least philosophically. You do this under the brand of religion because other modalities don't carry the same weight. Yes it comes with baggage but I think the pros outweigh the cons.
And then there is the community aspect that is needed, which is how I came up with a "Pinterest for beliefs". A place where you can find and post any belief you can think of and then collect them to your profile, edit them further, and discuss and refine them.
These approaches can take care of both the development and propagation of the new era of meaning.
